[PATCH] D79874: [RISCV] Add matching of codegen patterns to RISCV Bit Manipulation Zbs asm instructions

[Paolo Savini via Phabricator via llvm-commits]

PaoloS updated this revision to Diff 276892.
PaoloS added a comment.

Added pattern-matching for sbexti, sbclrw, sbsetw, sbinvw and sbextw.
Added correspondent codegen tests.
Reorganized the tests so that both 32 and 64 bit files have both 32 and 64 bit versions of each test.
Fixed some imprecise patterns due to unnecessary constant truncations.
