GlobalISel: Handle llvm.localescape

This one is pretty easy and shrinks the list of unhandled
intrinsics. I'm not sure how relevant the insert point is. Using the
insert position of EntryBuilder will place this after
constants. SelectionDAG seems to end up emitting these after argument
copies and before anything else, but I don't think it really
matters. This also ends up emitting these in the opposite order from
SelectionDAG, but I don't think that matters either.

This also needs a fix to stop the later passes dropping this as a dead
instruction. DeadMachineInstructionElim's version of isDead special
cases LOCAL_ESCAPE for some reason, and I'm not sure why it's excluded
from MachineInstr::isLabel (or why isDead doesn't check it).

I also noticed DeadMachineInstructionElim never considers inline asm
as dead, but GlobalISel will drop asm with no constraints.

[MLIR][Affine] Fix createPrivateMemRef in affine fusion

Always define a remapping for the memref replacement (`indexRemap`)
with the proper number of inputs, including all the `outerIVs`, so that
the number of inputs and the operands provided for the map don't mismatch.

BPF: support type exist/size and enum exist/value relocations

Four new CO-RE relocations are introduced:
  - TYPE_EXISTENCE: whether a typedef/record/enum type exists
  - TYPE_SIZE: the size of a typedef/record/enum type
  - ENUM_VALUE_EXISTENCE: whether an enum value of an enum type exists
  - ENUM_VALUE: the enum value of an enum type

These additional relocations will make CO-RE bpf programs
more adaptive for potential kernel internal data structure

[WebAssembly] Use "signed char" instead of "char" in SIMD intrinsics.

This allows people to use `int8_t` instead of `char`, -funsigned-char,
and generally decouples SIMD from the specialness of `char`.

And it makes intrinsics like `__builtin_wasm_add_saturate_s_i8x16`
and `__builtin_wasm_add_saturate_u_i8x16` use signed and unsigned
element types, respectively.

[SanitizerCoverage] Fix types of __stop* and __start* symbols

If a section is supposed to hold elements of type T, then the
corresponding CreateSecStartEnd()'s Ty parameter represents T*.
Forwarding it to GlobalVariable constructor causes the resulting
GlobalVariable's type to be T*, and its SSA value type to be T**, which
is one indirection too many. This issue is mostly masked by pointer
casts, however, the global variable still gets an incorrect alignment,
which causes SystemZ to choose wrong instructions to access the

Coverage reporting is broken, and is not easy to fix (see comment in
coverage.test). Interaction with sanitizers needs to be investigated
more thoroughly, since they appear to reduce coverage in certain cases.
