Subject: [PATCH 027/124] LoongArch: Rename frint_<fmt> to rint<mode>2

Use standard name so __builtin_rint{,f} can be expanded to one
instruction.

gcc/ChangeLog:

* config/loongarch/loongarch.md (frint_<fmt>): Rename to ..
	(rint<mode>2): .. this.

gcc/testsuite/ChangeLog:

* gcc.target/loongarch/frint.c: New test.
