In my opinion we should not warn for any asm that means the same both
as basic and as extended asm. The problem then becomes, what *is* the
meaning of a basic asm, what does it clobber.
Currently the only differences are:
- asms that have a % in the string, or {|} on targets with ASSEMBLER_DIALECT;
- ia64 (for stop bits);
- mep, and this one is easily fixed.
- basic asms do not get TARGET_MD_ASM_ADJUST.
