s390: Fix zero extend patterns using vlgv
In commit r16-2316-gc6676092318 mistakenly patterns were introduced
which actually should have been merged as alternatives to existing zero
extend patterns.
While on it, generalize the vec_extract patterns and also allow
registers for the index. A subsequent patch will add
register+immediate support.
gcc/ChangeLog:
* config/s390/s390.md: Merge movdi<mode>_zero_extend_A and
movsi<mode>_zero_extend_A into zero_extendsidi2 and
zero_extendhi<mode>2_z10 and
zero_extend<HQI:mode><GPR:mode>2_extimm.
* config/s390/vector.md (*movdi<mode>_zero_extend_A): Remove.
(*movsi<mode>_zero_extend_A): Remove.
(*movdi<mode>_zero_extend_B): Move to vec_extract patterns and
rename to *vec_extract<mode>_zero_extend.
(*movsi<mode>_zero_extend_B): Ditto.
gcc/testsuite/ChangeLog:
* gcc.target/s390/vector/vlgv-zero-extend-1.c: Require target
s390_mvx.
* gcc.target/s390/vector/vlgv-zero-extend-2.c: New test.
