aarch64: Add missing movmisalign patterns
The Advanced SIMD movmisalign patterns didn't handle 16-bit FP modes, which meant that the vector loop for: void test (_Float16 *data) { _Pragma ("omp simd") for (int i = 0; i < 8; ++i) data[i] = 1.0; } would be versioned for alignment. This was causing some new failures in aarch64/sve/single_5.c: FAIL: gcc.target/aarch64/sve/single_5.c scan-assembler-not \\tb FAIL: gcc.target/aarch64/sve/single_5.c scan-assembler-not \\tcmp FAIL: gcc.target/aarch64/sve/single_5.c scan-assembler-times \\tstr\\tq[0-9]+, 10 but I didn't look into what changed from earlier releases. Adding the missing modes removes some existing xfails. gcc/ * config/aarch64/aarch64-simd.md (movmisalign<mode>): Extend from VALL to VALL_F16. gcc/testsuite/ * gcc.target/aarch64/sve/single_5.c: Remove some XFAILs.
