re PR inline-asm/92615 (ICE in extract_insn)
PR target/92615
* config/i386/i386.c (ix86_md_asm_adjust): If dest_mode is
GET_MODE (dest), is not QImode, using ZERO_EXTEND and dest is not
register_operand, force x into register before storing it into dest.
Formatting fix.
* gcc.target/i386/pr92615.c: New test.
