Subject: [PATCH] [CIR][NFC] Use TableGen to generate LLVM lowering patterns
Most lowering patterns have exactly the same class declaration with different
names and different `matchAndRewrite` implementations, yet their declaration
occupies near 1000 lines of code in `LowerToLLVM.h`, making this file difficult
to read and boring to maintain. In this patch, I migrate their declarations to
be generated from `CIROps.td` using `clang-tblgen`. Some extra `CIR_Op` TableGen
fields are introduced to help this:
- The `CIR_Op` class now defines a `bit` field `hasLLVMLowering` which
defaults to `true`. If its value is `true`, `clang-tblgen` would generate an
LLVM lowering pattern declaration for the operation.
- Some LLVM lowering patterns has bounded recursion. This could be enabled by
setting the `isLLVMLoweringRecursive` field in a `CIR_Op` record to `true`.
- Some LLVM lowering patterns have defined additional class members. They
could be listed in the `extraLLVMLoweringPatternDecl` field.
Note that in the incubator we have a similar TableGen code generator that
generates LLVM lowering code for CIR builtin ops which has a one-to-one
correspondence to LLVM dialect operations. This patch does NOT try to upstream
it.
Some additional noticeable changes made by this patch:
- This patch adds the `dataLayout` member to every LLVM lowering pattern class
to make the job easier for a code generator. In the future we might want to
add more members to the lowering patterns, and we will need to update the
code generator to make such changes.
