[AArch64] Fix INSR for zero floats
We used INSR to handle zero integers but not zero floats.
2019-08-07 Richard Sandiford <richard.sandiford@arm.com>
gcc/
* config/aarch64/constraints.md (Z): Handle floating-point zeros too.
* config/aarch64/predicates.md (aarch64_reg_or_zero): Likewise.
gcc/testsuite/
* gcc.target/aarch64/sve/init_13.c: New test.
