Eric Fiselier	a016efb1dc	[Libc++] Use #pragma push_macro/pop_macro to better handle min/max on Windows ... Summary: This patch improves how libc++ handles min/max macros within the headers. Previously libc++ would undef them and emit a warning. This patch changes libc++ to use `#pragma push_macro` to save the macro before undefining it, and `#pragma pop_macro` to restore the macros and the end of the header.

Eric Fiselier	50d61da2e4	Fix GCC 7 test failures. ... This patch fixes the test failures and unexpected passes that occur when testing against GCC 7. Specifically: * don't mark __gcd as always inline because it's a recursive function. GCC diagnoses this. * don't XFAIL the aligned allocation tests. GCC 7 supports them but not the -faligned-allocation option. * Work around gcc.gnu.org/PR78489 in variants constructors. llvm-svn: 302488	2017-05-09 00:00:00 +00:00
