LoongArch: Replace UNSPEC_FCOPYSIGN with copysign RTL
When I added copysign support for LoongArch (r13-3702), we did not have
a copysign RTL insn, so I had to use UNSPEC to represent the copysign
instruction. Now the copysign RTX code has been added in r14-1586, so
this patch removes those UNSPECs, and it uses the native RTL copysign
insn.
Inspired by rs6000 patch "Cleanup: Replace UNSPEC_COPYSIGN with copysign
RTL" [1] from Michael Meissner.

gcc/ChangeLog:
* config/loongarch/loongarch.md (UNSPEC_FCOPYSIGN): Delete.
(copysign<mode>3): Use copysign RTL instead of UNSPEC.
