aarch64: Add QI -> HI zero-extension for LDAPR
This patch is a straightforward extension of the zero-extending LDAPR
pattern to represent QI -> HI load-extends. This maps down to a LDAPRB-W
instruction.
This lets us remove a redundant zero-extend in the new test function.
Bootstrapped and tested on aarch64-none-linux-gnu.
gcc/ChangeLog:
* config/aarch64/atomics.md
(*aarch64_atomic_load<ALLX:mode>_rcpc_zext):
Use SD_HSDI for destination mode iterator.
gcc/testsuite/ChangeLog:
* gcc.target/aarch64/ldapr-zext.c: Add test for u8 to u16
extension.
