LoongArch: Set default alignment for functions jumps and loops [PR112919].
Xi Ruoyao set the alignment rules under LA464 in commit r14-1839,
but the macro ASM_OUTPUT_ALIGN_WITH_NOP was removed in R14-4674,
which affected the alignment rules.
So I set different aligns on LA464 and LA664 again to test the
performance of spec2006, and modify the alignment based on the test
results.
gcc/ChangeLog:
PR target/112919
* config/loongarch/loongarch-def.cc (la664_align): Newly defined
function that sets alignment rules under the LA664 microarchitecture.
* config/loongarch/loongarch-opts.cc
(loongarch_target_option_override): If not optimizing for size, set
the default alignment to what the target wants.
* config/loongarch/loongarch-tune.h (struct loongarch_align): Add
new member variables jump and loop.
