Revert r280944 - Added 'inline' attribute to basic_string's destructor

This patch causes a couple of issues:

1) It triggers http://llvm.org/PR30341. Although the bug is not truly a libc++
bug it breaks the LLVM build using libc++. Reverting this patch is only
a temporary workaround until Clang is fixed.

2) It adds yet another ABI incompatibility when libc++.so is compiled with GCC.
Specifically GCC doesn't ignore the _LIBCPP_INLINE_VISIBILITY on the out-of-line
definition when compiling the dylib. This causes the externally instantiated
~basic_string symbol to have hidden visibility.

This patch should be recommitted after addressing (1) and (2). (2) can be fixed
by adding _LIBCPP_EXTERN_TEMPLATE_INLINE_VISIBILITY which is defined as
__attribute__((visibility("default"), always_inline)) as opposed to
_LIBCPP_INLINE_VISIBILITY which makes the symbol hidden.

[MC] Handle discardable COFF sections in assembly

Summary:
This fixes a dumpbin warning on objects produced by the MC assembler
when starting from text. All .debug$S sections are supposed to be marked
IMAGE_SCN_MEM_DISCARDABLE. The main, non-COMDAT .debug$S section had
this set, but any comdat ones were not being marked discardable because
there was no .section flag for it.

This change does two things:

- If the section name starts with .debug, implicitly mark the section as
  discardable. This means we do the same thing as gas on .s files with
  DWARF from GCC, which is important.

- Adds the 'D' flag to the .section directive on COFF to explicitly say
  a section is discardable. We only emit this flag if the section name
  does not start with .debug. This allows the user to explicitly tweak
  their section flags without worrying about magic section names.

The only thing you can't do in this scheme is to create a
non-discardable section with a name starting with ".debug", but
hopefully users don't need that.
