[PATCH] D79875: [RISCV] Add matching of codegen patterns to RISCV Bit Manipulation Zbt asm instructions

[Paolo Savini via Phabricator via llvm-commits]

PaoloS updated this revision to Diff 277534.
PaoloS added a comment.

Updated the test:

- the tests have been updated from the top of all the sub-patches together so that they are exactly the same as they would be if updated with the whole final patch.
- labels specific to the sub-extension have been added alongside the generic RISCVIB label (that activates all the sub-extensions) so that we can see how differently the patterns are matched with the specific subextension or with all of them together.
- the tests will probably fail if run by checking out the commit of a subextension and if updated they'll change. These tests are designed to work with the final squashed patch.

Added pattern-matching for fslw, fsrw, fsri and fsriw
Added the correspondent tests.
Corrected the order of the patterns.
