Add a new flag, -fms-inline-asm, that enables the output of MS-style inline
assembly.
By default, we don't emit IR for MS-style inline assembly (see r158833 as to
why). This is strictly for testing purposes and should not be enabled with the
expectation that things will work. This is a temporary flag and will be removed
once MS-style inline assembly is fully supported.
