riscv: bitmanip: Remove duplicate zero_extendhi<GPR:mode>2 pattern
We currently have two identical zero_extendhi<GPR:mode>2 patterns:
* '*zero_extendhi<GPR:mode>2_zbb'
* '*zero_extendhi<GPR:mode>2_bitmanip'
This patch removes the *_zbb pattern and ensures that all sign- and
zero-extensions use the postfix '_bitmanip'.
Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu>
gcc/ChangeLog:
* config/riscv/bitmanip.md (*extend<SHORT:mode><SUPERQI:mode>2_zbb):
Rename postfix to _bitmanip.
(*extend<SHORT:mode><SUPERQI:mode>2_bitmanip): Renamed pattern.
(*zero_extendhi<GPR:mode>2_zbb): Remove duplicated pattern.
