  tcg: correctly mark dead inputs for mov with a constant

When tcg_reg_alloc_mov propagate a constant, we failed to correctly mark
a temp as dead if the liveness analysis hints so. This fixes the
following assert when configure with --enable-debug-tcg:

  qemu-x86_64: tcg/tcg.c:1827: tcg_reg_alloc_bb_end: Assertion `ts->val_type == 
TEMP_VAL_DEAD' failed.

  tcg: mark temps as mem_coherent = 0 for mov with a constant

When a constant has to be loaded in a mov op, we fail to set
mem_coherent = 0. This patch fixes that.
