re PR inline-asm/8832 (traditional "asm volatile" code is illegally optimized)
PR inline-asm/8832
* tree.h (expand_asm): New prototype.
* stmt.c (expand_asm): Set the MEM_VOLATILE_P flag if instructed
to do so.
* c-semantics (genrtl_asm_stmt): Pass the RID_VOLATILE qualifier
down to expand_asm.
* c-typeck.c (simple_asm_stmt): Set the RID_VOLATILE qualifier.
* rtlanal.c (volatile_insn_p) [ASM_INPUT]: Test the MEM_VOLATILE_P flag.
(volatile_refs_p) [ASM_INPUT]: Likewise.
(side_effects_p) [ASM_INPUT]: Likewise.
