[CIR] Fix build error

[YazZz1k]

Currently build on main branch fails with the the error:

[602/787] Linking CXX shared library lib/libMLIRCIR.so.18git
FAILED: lib/libMLIRCIR.so.18git
...
ld.lld: error: undefined symbol: mlir::cir::CIRCallOpInterface::getNumArgOperands()

This PR fixes this issue

Currently with this fix I got another error

FAILED: lib/libMLIRCIRInterfaces.so.18git
...
ld.lld: error: undefined symbol: mlir::detail::TypeIDResolver<mlir::cir::ConditionOp, void>::id
>>> referenced by CIROps.h.inc:2791 (tools/clang/include/clang/CIR/Dialect/IR/CIROps.h.inc:2791)
>>>               tools/clang/lib/CIR/Interfaces/CMakeFiles/obj.MLIRCIRInterfaces.dir/CIRLoopOpInterface.cpp.o:(mlir::detail::TypeIDResolver<mlir::cir::ConditionOp, void>::resolveTypeID())

Looks like this new errors appear while code refactoring on the one of commits from 5d332db to d54606d

@YazZz1k could you paste your CMake configuration command here? I wasn't able to reproduce this build error.

@sitio-couto Hello! My CMake config:

cmake -G Ninja -DCMAKE_BUILD_TYPE=Debug -DLLVM_USE_LINKER=lld -DBUILD_SHARED_LIBS=ON -DLLVM_USE_SPLIT_DWARF=ON -DLLVM_OPTIMIZED_TABLEGEN=ON -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_CCACHE_BUILD=OFF -DLLVM_TARGETS_TO_BUILD="AArch64;ARM;X86" -DLLVM_ENABLE_PROJECTS="clang;lld;mlir;cir" ../llvm

@YazZz1k could you paste your CMake configuration command here? I wasn't able to reproduce this build error.

I think the crash was due to -DBUILD_SHARED_LIBS=ON, this build variant is more sensitive to missing dependencies.

@YazZz1k Thanks for the PR! I found the same issue and fixed it in 77c8438 and e5dd626 earlier!
