[PATCH] D14411: Use __attribute__((internal_linkage)) when available.

[Evgeniy Stepanov via cfe-commits]

eugenis added a dependency: D12502: [libcxx] Better constain tuples constructors -- Fix PR23256 and PR22806.
eugenis added a comment.

Note, this breaks tuple_cat.pass.cpp test.

With -O0, replacing always_inline with internal_linkage results in less optimization being done (namely, no inlining happens). This ends up exposing

  https://llvm.org/bugs/show_bug.cgi?id=23256

which is fixed by

  http://reviews.llvm.org/D12502

The same failure can be reproduced in the current ToT libc++ by running this test with -O2.

This change depends on http://reviews.llvm.org/D12502.
