cmd/compile/internal/ssa: fix PPC64 shift codegen regression
CL 621357 introduced new generic lowering rules which caused
several shift related codegen test failures.
Add new rules to fix the test regressions, and cleanup tests
which are changed but not regressed. Some CLRLSLDI tests are
removed as they are no test CLRLSLDI rules.
Fixes #70003
