MIPS: Output $0 for conditional trap if !ISA_HAS_COND_TRAPI
MIPSr6 removes condition trap instructions with imm, so the instruction
like `teq $2,imm` will be converted to
li $at, imm
teq $2, $at
The current version of Gas cannot detect if imm is zero, and output
teq $2, $0
Let's do it in GCC.
gcc
* config/mips/mips.md(conditional_trap_reg): Output $0 instead
of 0 if !ISA_HAS_COND_TRAPI.
