[MIPS] Disable -mbranch-likely for -Os when targetting generic arch
gcc/
* config/mips/mips-cpus.def: Replace PTF_AVOID_BRANCHLIKELY with
PTF_AVOID_BRANCHLIKELY_ALWAYS for generic architecture and with
PTF_AVOID_BRANCHLIKELY_SPEED for others.
(mips2, mips3, mips4): Add PTF_AVOID_BRANCHLIKELY_SIZE to tune flags.
* config/mips/mips.c (mips_option_override): Enable the branch likely
depending on the tune flags and optimization level.
* config/mips/mips.h (PTF_AVOID_BRANCHLIKELY): Remove.
(PTF_AVOID_BRANCHLIKELY_SPEED): Define.
(PTF_AVOID_BRANCHLIKELY_SIZE): Likewise.
(PTF_AVOID_BRANCHLIKELY_ALWAYS): Likewise.

But the trunk GCC 8.X version is right. continue bisect which version fix this.
