MIPS: Predefine __mips_strict_alignment if STRICT_ALIGNMENT
Arm32 predefines __ARM_FEATURE_UNALIGNED if -mno-unaligned-access,
and RISC-V predefines __riscv_misaligned_avoid.
Let's define __mips_strict_alignment for MIPSr6 and -mstrict-align
is used.
Note that, this macro is always defined for pre-R6.
gcc
* config/mips/mips.h (TARGET_CPU_CPP_BUILTINS): Predefine
__mips_strict_alignment if STRICT_ALIGNMENT.
