[Patch libgcc] Enable HCmode multiply and divide (mulhc3/divhc3)
This patch arranges for half-precision complex multiply and divide
routines to be built if __LIBGCC_HAS_HF_MODE__. This will be true
if the target supports the _Float16 type.
libgcc/
PR target/63250
* Makefile.in (lib2funcs): Build _mulhc3 and _divhc3.
* libgcc2.h (LIBGCC_HAS_HF_MODE): Conditionally define.
(HFtype): Likewise.
(HCtype): Likewise.
(__divhc3): Likewise.
(__mulhc3): Likewise.
* libgcc2.c: Support _mulhc3 and _divhc3.
