#3 0x0000000000d0a0bf in expand_asm_stmt (stmt=0x7ffff667f0b0)

3287 allows a register, make a temporary to act as an intermediate.
3288 Make the asm insn write into that, then we will copy it to
3289 the real output operand. Likewise for promoted variables. */

looks like a remanent from before MEM_REF times?

fixes this, not sure how "careful" we want to be here (TARGET_MEM_REF?
What about other tcc_reference codes?).
I'm going to test REFERENCE_CLASS_P.
