Topical: http://clang-developers.42468.n3.nabble.com/libclang-crash-when-parsing-MS-style-inline-assembly-td4035432.html#a4035754

I never got around to checking if LLVMInitialize* do fail silently in
the absence of X86 target support, so I can't tell what happens there.
Actual asm parsing seems to be short-circuited if target info is not
available.
