Remove '*' from movsi/di/ti patterns
Remove the remaining uses of '*' from the movsi/di/ti patterns.
Using '*' in alternatives is typically incorrect at it tells the register
allocator to ignore those alternatives. So remove these from all the
integer move patterns. This removes unnecessary int to float moves, for
example gcc.target/aarch64/pr62178.c no longer generates a redundant fmov
since the w = m variant is now allowed.
gcc/
* config/aarch64/aarch64.md (movsi_aarch64): Remove all '*'.
(movdi_aarch64): Likewise.
(movti_aarch64): Likewise.
