target-arm: A64: Add 1-source 32-to-32 and 64-to-64 FP instructions
This patch adds support for those instructions in the "Floating-point
data-processing (1 source)" group which are simple 32-bit-to-32-bit
or 64-bit-to-64-bit operations (ie everything except FCVT between
single/double/half precision).
We put the new round-to-int helpers in helper.c because they will
also be used by the new ARMv8 A32/T32 rounding instructions.
