Jonas Hahnfeld dbeb64d2da Fix FormatVariadicTest with GCC
Looks like GCC didn't like the original specialization, try within namespace.

Daniel Sanders d66e0901ae [globalisel][tablegen] Import stores and allow GISel to automatically substitute zero regs like WZR/XZR/$zero.
This patch enables the import of stores. Unfortunately, doing so by itself,
loses an optimization where storing 0 to memory makes use of WZR/XZR.

To mitigate this, this patch also introduces a new feature that allows register
operands to nominate a zero register. When this is done, GlobalISel will
substitute (G_CONSTANT 0) with the nominated register automatically. This
is currently configured to only apply to the stores.

Applying it to GPR32/GPR64 register classes in general will be done after
review see (https://reviews.llvm.org/D39150).

A wasm file crafted with a bogus section size can trigger an ASan issue

Alex Shlyapnikov 028c4cddad [Sanitizers] New sanitizer API to purge allocator quarantine.
Summary:
Purging allocator quarantine and returning memory to OS might be desired
between fuzzer iterations since, most likely, the quarantine is not
going to catch bugs in the code under fuzz, but reducing RSS might
significantly prolong the fuzzing session.

This patch adds one additional case - if both BUILD_VECTORs represent splats of the same scalar value but with different UNDEF elements, then we should create a single splat BUILD_VECTOR, sharing only the UNDEF elements defined by the shuffle mask.

Martin Storsjo ddb094ad36 [COFF] Fix exporting of functions starting with underscores, etc
This fixes exporting functions in the following cases:
- functions starting with an underscore in def files
- functions starting with an underscore, via dllexport attributes, for mingw
- fastcall and vectorcall functions when declared undecorated in def files
- vectorcall functions when declared decorated in def files
- stdcall functions when declared decorated in def files for mingw

This still exports the stdcall functions with the wrong name
in the normal msvc/link.exe mode, if declared with decoration in
the def file though (this is not a regression though). Exporting
functions via def files including decoration is not something I
believe is routinely done though, but is tested to try to match
link.exe's behaviour as far as easily possible.
