scudo: Add initial memory tagging support.
When the hardware and operating system support the ARM Memory Tagging
Extension, tag primary allocation granules with a random tag. The
granules either side of the allocation are tagged with tag 0, which is
normally excluded from the set of tags that may be selected randomly.
Memory is also retagged with a random tag when it is freed, and we
opportunistically reuse the new tag when the block is reused to reduce
overhead. This causes linear buffer overflows to be caught
deterministically and non-linear buffer overflows and use-after-free to
be caught probabilistically.
This feature is currently only enabled for the Android allocator and
depends on an experimental Linux kernel branch available here:
All code that depends on the kernel branch is hidden behind a macro,
ANDROID_EXPERIMENTAL_MTE. This is the same macro that is used by the
Android platform and may only be defined in non-production
configurations. When the userspace interface is finalized the code will
be updated to use the stable interface and all #ifdef

Factor out renaming logic from readability-identifier-naming
Before this patch, readability-identifier-naming contained a significant
amount of logic for (a) checking the style of identifiers, followed by
(b) renaming/ applying fix-its. This patch factors out (b) into a
separate base class so that it can be reused by other checks that want
to do renaming. This also cleans up readability-identifier-naming
significantly, since now it only needs to be concerned with the
interesting details of (a).

[IR] fix crash in Constant::isElementWiseEqual() with FP types
We lifted this code from InstCombine for general usage in: rL369842
...but it's not safe as-is. There are no existing users that can trigger
this bug, but I discovered it via crashing several regression tests when
trying to use it for select folding in InstSimplify.
ICmp requires (vector) integer types, so give up on anything that's not
integer or FP (pointers and ?) then bitcast the constants before trying
the match. That matches the definition of "equal or undef" that I was
looking for. If someone wants an FP-aware version of equality (deal with
NaN, -0.0), that could be a different mode or different function.

[WebAssembly] Track frame registers through VReg and local allocation
This change has 2 components:
Target-independent: add a method getDwarfFrameBase to
TargetFrameLowering. It describes how the Dwarf frame base will be
encoded.  That can be a register (the default), the CFA (which replaces
NVPTX-specific logic in DwarfCompileUnit), or a DW_OP_WASM_location
WebAssembly: Allow WebAssemblyFunctionInfo::getFrameRegister to return
the correct virtual register instead of FP32/SP32 after
WebAssemblyReplacePhysRegs has run.  Make WebAssemblyExplicitLocals
store the local it allocates for the frame register. Use this local
information to implement getDwarfFrameBase
The result is that the DW_AT_frame_base attribute is correctly encoded
for each subprogram, and each param and local variable has a correct
DW_AT_location that uses DW_OP_fbreg to refer to the frame base.

AMDGPU: Move permlane discard vdst_in optimization
This case can be handled as a regular selection pattern, so move it out
of the weird post-isel folding code which doesn't have an exactly
equivalent place in GlobalISel.
I think it doesn't make much sense to do this optimization here though,
and it would be more useful in instcombine. There's not really any new
information that will be gained during lowering since these inputs were
known from the beginning.
