Empty assembly string will not introduce assembly code in the output
binary and it is often used as a trick in the header to disable
optimizations. It doesn't conflict with the purpose of the option so it
is allowed with -fno-gnu-inline-asm flag.

Summary:
AsmLabel is heavily used in system level and firmware to redirect
function and access platform specific labels. They are also extensively
used in system headers which makes this option unusable for many
users. Since AsmLabel doesn't introduce any assembly code into the
output binary, it shouldn't be considered as inline-asm.

Summary:
FileScopeAsm should be treated the same as funcion level inline asm.
-fno-gnu-inline-asm should trigger an error if file scope asm is used.
I missed this case from r226340. This should not affect ms-extension
because it is not allowed in the file scope.
