[AArch64] Add more SVE FMLA and FMAD /z alternatives
This patch makes the floating-point conditional FMA patterns provide the
same /z alternatives as the integer patterns added by a previous patch.
We can handle cases in which individual inputs are allocated to the same
register as the output, so we don't need to force all registers to be
different.

* config/aarch64/aarch64-sve.md
(*cond_<SVE_COND_FP_TERNARY:optab><SVE_F:mode>_any): Add /z
alternatives in which one of the inputs is in the same register
as the output.
gcc/testsuite/
* gcc.target/aarch64/sve/cond_mla_5.c: Allow FMAD as well as FMLA
and FMSB as well as FMLS.
