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.
