Cherry-pick upstream commit llvm-svn: 266891:

[PATCH] builtins: remove use of __attribute__((pcs("aapcs"))) on
 Windows

Windows does not honour the __attribute__((pcs)) on ARM.  Although this will
result in ABI mismatches, compiler-rt should largely be unneeded for resolving
dependencies as we generate MS ABI compliant library calls now for the most
part.
