[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.
