[ARM] Improve max_cond_insns setting for Cortex cores
To enable cores to use the correct max_cond_insns setting, use the core-specific
tuning when a CPU/tune is selected unless -mrestrict-it is explicitly set.
On Cortex-A57 this gives 1.1% performance gain on SPECINT2006 as well as a
0.4% codesize reduction.
gcc/
* config/arm/arm.c (arm_option_override_internal):
Use max_cond_insns from CPU tuning unless -mrestrict-it is used.
From-SVN: r278968
