[zorg] Add extra argument passing to getAnnotatedBuildFactory.

Summary:
This allows the passing of extra arguments from builders to annotated script runners.
Originally I was planning on adding the ability to pass `extra_cmake_args`, however this approach seems more general to fit many needs.
For libc builders this will allow us to pass `--asan` and in the script this will add in the `extra_cmake_args`.

[BasicAA] Make BasicAA a cfg pass.

Summary:
Part of the changes in D44564 made BasicAA not CFG only due to it using
PhiAnalysisValues which may have values invalidated.
Subsequent patches (rL340613) appear to have addressed this limitation.

BasicAA should not be invalidated by non-CFG-altering passes.
A concrete example is MemCpyOpt which preserves CFG, but we are testing
it invalidates BasicAA.

Allow retrieving source files relative to the compilation directory.

Summary:
Dwarf stores source-file names the three parts:
<compilation_directory><include_directory><filename>

Prior to this change, the code only allowed retrieving either all
three as the absolute path, or just the filename.  But many
compile-command lines--especially those in hermetic build systems
don't specify an absolute path, nor just the filename, but rather the
path relative to the compilation directory. This features allows
retrieving them in that style.

Add tests for path printing styles.

Modify createBasicPrologue to handle include directories.

[libc++] Unbreak test suite (CWG1423)

clang 9ce6dc9872be4081fb98f6161c28581e1cbbe7dc drops support for
implicit conversion of nullptr_t to bool. From that commit:

    The C++ rules briefly allowed this, but the rule changed nearly 10
    years ago and we never updated our implementation to match. However,
    we've warned on this by default for a long time, and no other compiler
    accepts (even as an extension).

[AMDGPU] Fix implicit operands for ENTER_WWM pseudo

Summary:
SIInstrInfo::expandPostRAPseudo converts ENTER_WWM in-place into an
S_OR_SAVEEXEC instruction that needs certain implicit operands. Without
this patch I get errors like this that make it harder to use -stop-after
to bisect the pass pipeline:

$ llc -march=amdgcn test/CodeGen/AMDGPU/wqm.ll -stop-after=postrapseudos -o - | sed -E 's/ (from|into) custom "TargetCustom[0-9]+"//' | llc -march=amdgcn -x=mir
error: <stdin>:1295:70: missing implicit register operand 'implicit-def $scc'
    renamable $sgpr2_sgpr3 = S_OR_SAVEEXEC_B64 -1, implicit-def $exec

Note that this error is currently only generated by MIParser but it
comes with a FIXME comment:

[OPENMP50]Full handling of atomic_default_mem_order in requires
directive.

According to OpenMP 5.0, The atomic_default_mem_order clause specifies the default memory ordering behavior for atomic constructs that must be provided by an implementation. If the default memory ordering is specified as seq_cst, all atomic constructs on which memory-order-clause is not specified behave as if the seq_cst clause appears. If the default memory ordering is specified as relaxed, all atomic constructs on which memory-order-clause is not specified behave as if the relaxed clause appears.
If the default memory ordering is specified as acq_rel, atomic constructs on which memory-order-clause is not specified behave as if the release clause appears if the atomic write or atomic update operation is specified, as if the acquire clause appears if the atomic read operation is specified, and as if the acq_rel clause appears if the atomic captured update operation is specified.

[ORC] Add debug logging to JITDylib::addDependencies.

[JITLink] Add an assertion that block removal leaves no dangling symbols.

[ORC] Fix symbol dependence propagation algorithm in ObjectLinkingLayer.

ObjectLinkingLayer was not correctly propagating dependencies through local
symbols within an object. This could cause symbol lookup to return before a
searched-for symbol is ready if the following conditions are met:
(1) The definition of the symbol being searched for transitively depends on a
    local symbol within the same object, and that local symbol in turn
    transitively depends on an external symbol provided by some other module
    in the JIT.
(2) Concurrent compilation is enabled.
(3) Thread scheduling causes the lookup of the searched-for symbol to return
    before all transitive dependencies of the looked-up symbol are emitted.

This bug was found by inspection and has not been observed in practice.

A jitlink test case has been added to verify that symbol dependencies are
correctly propagated through local symbol definitions.

[NFC] Delete extra white space in a test case.

Remove an extra empty line in one of the AIX driver test cases.

[mlir][VectorOps] Adds canonicalization rewrite patterns for vector ShapeCastOp.

*) ShapeCastOp folder: folds canceling shape cast ops (e.g. shape_cast A -> B followed by shape_cast B -> A) away.

[Attributor] Identify dead uses in PHIs (almost) based on dead edges

[RISCV] Add support for save/restore of callee-saved registers via libcalls

This patch adds the support required for using the __riscv_save and
__riscv_restore libcalls to implement a size-optimization for prologue
and epilogue code, whereby the spill and restore code of callee-saved
registers is implemented by common functions to reduce code duplication.

Logic is also included to ensure that if both this optimization and
shrink wrapping are enabled then the prologue and epilogue code can be
safely inserted into the basic blocks chosen by shrink wrapping.

[DebugInfo] Call site entries cannot be generated for FrameSetup calls

Instructions marked as FrameSetup do not cause requestLabelAfterInsn to
be called and so no such label is generated. Call instructions which
require call site entries to be generated require this label to be
present in order to calculate the return PC offset/address, but the
check for whether the call instruction is marked as FrameSetup was not
present.

Therefore in the case where a call instruction is marked as FrameSetup,
an assertion failure occurs if a call site entry is to be generated.
This is the case with RISC-V's implementation of save/restore via
library calls.
