[AArch64] Catch attempts to use SVE types when SVE is disabled
This patch reports an error if code tries to use variable-length
SVE types when SVE is disabled. We already report a similar error
for definitions or uses of SVE functions when SVE is disabled.

gcc/
* config/aarch64/aarch64.c (aarch64_report_sve_required): New function.
(aarch64_expand_mov_immediate): Use it when attempting to measure
the length of an SVE vector.
(aarch64_mov_operand_p): Only allow SVE CNT immediates when
SVE is enabled.
gcc/testsuite/
* gcc.target/aarch64/sve/acle/general/nosve_4.c: New test.
* gcc.target/aarch64/sve/acle/general/nosve_5.c: Likewise.
* gcc.target/aarch64/sve/pcs/nosve_4.c: Expected a second error
for the copy.
* gcc.target/aarch64/sve/pcs/nosve_5.c: Likewise.
* gcc.target/aarch64/sve/pcs/nosve_6.c: Likewise.
