[MLIR][ControlFlowToLLVM] Remove typed pointer support (#70733) 
This commit removes the support for lowering ControlFlow to LLVM dialect
with typed pointers. Typed pointers have been deprecated for a while now
and it's planned to soon remove them from the LLVM dialect.

1fdbbd158d [mlir][Conversion] Implement ConvertToLLVMPatternInterface for FuncDialect 
Also a new pass option `ConvertToLLVMPass` to populate only patterns from the specified dialects. This is needed because the existing test cases expect that only ops from certain dialects are lowered. (E.g., "arith-to-llvm" expects that only "arith" ops are lowered but not "func" ops.)

c4769ef59c [mlir][Conversion] Re-submit: Implement ConvertToLLVMPatternInterface (1) 
This is a resubmit of the original D157391 change, which was reverted
because it needed special handling for the async dialect. (I removed it
from this change.)

Implement ConvertToLLVMPatternInterface for more dialects: arith,
complex, cf.

f0ceba8be6 Revert "[mlir][Conversion] Implement ConvertToLLVMPatternInterface (1)" 
This reverts commit 52aa6bd3fd6f48f583beaadcbb53edc0f3def4a1.

async-to-llvm needs special handling as it uses the type converter in a
different way.

cbd7aaaceb [mlir][cf] Add support for opaque pointers to ControlFlowToLLVM lowering 
Part of https://discourse.llvm.org/t/rfc-switching-the-llvm-dialect-and-dialect-lowerings-to-opaque-pointers/68179

This is a very simple patch since there is only one use of pointers types in `cf.assert` that has to be changed. Pointer types are conditionally created with element types and the GEP had to be adjusted to use the array type as base type.
