  [MC] Add .pushsection/.popsection support to COFFAsmParser

The COFFAsmParser (to my surprise) didn't support the .pushsection and
.popsection directives. These directives aren't directly useful, however for
frontends that have inline asm support this is really useful. Rust in
particular, has support for inline asm, which can be used together with these
directives to "emulate" features like static generics. This patch adds support
for the two mentioned directives.
