  Changed paths:
    M target/hexagon/gen_tcg.h
    M target/hexagon/gen_tcg_funcs.py
    M target/hexagon/macros.h
    M target/hexagon/translate.c

  Log Message:
  -----------
  Hexagon (target/hexagon) more tcg_constant_*

Change additional tcg_const_tl to tcg_constant_tl

Note that gen_pred_cancal had slot_mask initialized with tcg_const_tl.
However, it is not constant throughout, so we initialize it with
tcg_temp_new and replace the first use with the constant value.

  Log Message:
  -----------
  Hexagon (target/hexagon) put writes to USR into temp until commit

Change SET_USR_FIELD to write to hex_new_value[HEX_REG_USR] instead
of hex_gpr[HEX_REG_USR].

Then, we need code to mark the instructions that can set implicitly
set USR
- Macros added to hex_common.py
- A_FPOP added in translate.c

Test case added in tests/tcg/hexagon/overflow.c
