[PATCH] libstdc++: Make <meta> header compatible with -fno-asm

[Jonathan Wakely]

We currently only use 'asm' in .cc files (where we control the build
flags) and in the experimental::simd headers. We could just say that
-fno-asm is not compatible with libstdc++ and so using it is not
supported, but we can also just make this small change.

libstdc++-v3/ChangeLog:

	* include/std/meta (exception::what, access_context::via): Use
	__asm__ instead of asm keyword.

Tested x86_64-linux.
