Log message:
* doc/extend.texi (Extended Asm): Clarify that overlap between
asm-declared register variables used in an asm and the asm clobber
list is not allowed.
* stmt.c (decl_conflicts_with_clobbers_p): New function.
(expand_asm_operands): Keep track of clobbered registers. Call
decl_conflicts_with_clobbers_p for each input and output operand.
If no conflicts found before, also do conflict sanity check when
emitting clobbers.
