Summary: Backport mingw fixes for compiler-rt profile library
to 13.x
Product: compiler-rt

Hardware: PC
OS: All

The compiler-rt profile library is broken in 13.x for mingw targets. These two
commits need to be backported to remedy it:
commit 94c001d6465857459617e9858e5128a784400e54
Author: Martin Storsjö <mar...@martin.st>

[profile] Build with -fms-extensions in MinGW mode
commit 4cfb047d6ab3259c20059e8ed4c15ece3d6eb723

[profile] Don't use pragma comment linker on mingw
Out of these two commits, the latter undoes the former and does fix the same
issue differently - but I guess it's simplest to just cherrypick them both in
that order. (The first fix only works when built with clang and linked with
lld, but the latter fixes building with GCC and linking with ld.bfd.)
