MIPS: Remove -m(no-)lra option
PR target/113955
The `-mlra` option was introduced in 2014 for MIPS, and was set to
default since then. It's time for us to drop no-lra support by
dropping -m(no-)lra options.
gcc:
* config/mips/mips.cc(mips_option_override):
Drop mips_lra_flag variable;
(mips_lra_p): Removed.
(TARGET_LRA_P): Remove definition here to use the default one.
* config/mips/mips.md(*mul_acc_si, *mul_acc_si_r3900, *mul_sub_si):
Drop mips_lra_flag variable.
* config/mips/mips.opt(-mlra): Removed.
* config/mips/mips.opt.urls(mlra): Removed.
