[pushed] aarch64: Restore generation of SVE UQDEC instructions
Checks
Commit Message
The addition of TARGET_CSSC meant that we wouldn't generate SVE
UQDEC instructions unless +cssc was also enabled.
Fixes:
- gcc.target/aarch64/sve/slp_4.c
- gcc.target/aarch64/sve/slp_10.c
- gcc.target/aarch64/sve/while_4.c
Tested on aarch64-linux-gnu & pushed.

* config/aarch64/aarch64.md (umax<mode>3): Separate the CNT and CSSC
tests.
