[clang] [CIR] Add missing MLIR TableGen dependencies to CIR CMake targets (PR #187692)

[Morris Hafner via cfe-commits]

https://github.com/mmha created https://github.com/llvm/llvm-project/pull/187692

CIR targets include MLIR headers that depend on TableGen-generated .inc files (BuiltinLocationAttributes.h.inc, BytecodeOpInterface.h.inc), but do not declare build dependencies on the corresponding TableGen targets. This causes intermittent build failures with parallel builds when the .inc files have not yet been generated by the time CIR sources compile.

Add MLIRBuiltinLocationAttributesIncGen and MLIRBytecodeOpInterfaceIncGen to DEPENDS in all affected CIR CMake targets:
- clangCIRLoweringCommon
- clangCIRLoweringDirectToLLVM
- clangCIRFrontendAction
- MLIRCIRInterfaces
- MLIRCIR (Dialect/IR)
- MLIRCIRTransforms
- MLIRCIRTargetLowering
- CIROpenACCSupport
- clangCIR (CodeGen)

Subject: [PATCH] [CIR] Add missing MLIR TableGen dependencies to CIR CMake
 targets

CIR targets include MLIR headers that depend on TableGen-generated .inc
files (BuiltinLocationAttributes.h.inc, BytecodeOpInterface.h.inc), but
do not declare build dependencies on the corresponding TableGen targets.
This causes intermittent build failures with parallel builds when the
.inc files have not yet been generated by the time CIR sources compile.

Add MLIRBuiltinLocationAttributesIncGen and MLIRBytecodeOpInterfaceIncGen
to DEPENDS in all affected CIR CMake targets:
- clangCIRLoweringCommon
- clangCIRLoweringDirectToLLVM
- clangCIRFrontendAction
- MLIRCIRInterfaces
- MLIRCIR (Dialect/IR)
- MLIRCIRTransforms
- MLIRCIRTargetLowering
- CIROpenACCSupport
- clangCIR (CodeGen)
