[soft-fp] Add support for various half-precision conversion routines.
This patch adds conversion routines required for _Float16 support in AArch64. These are one-step conversions to and from TImode and TFmode. We need these on AArch64 regardless of presence of the ARMv8.2-A 16-bit floating-point extensions. In the patch, soft-fp/half.h is derived from soft-fp/single.h . The conversion routines are derivatives of their respective SFmode variants. * soft-fp/extendhftf2.c: New. * soft-fp/fixhfti.c: Likewise. * soft-fp/fixunshfti.c: Likewise. * soft-fp/floattihf.c: Likewise. * soft-fp/floatuntihf.c: Likewise. * soft-fp/half.h: Likewise. * soft-fp/trunctfhf2.c: Likewise.
