CheckAsmLValue - GNU C has an extremely ugly extension whereby they silently ignore "noop" casts in places where an lvalue is required by an inline asm.
We emulate this behavior when -fheinous-gnu-extensions is specified, but provide a strong guidance to not use it.
This method checks to see if the argument is an acceptable l-value and returns false if it is a case we can handle.
