This patch adds the initial CIRGen support for pointer-to-member-functions. It
contains the following new types, attributes, and operations:
- `!cir.method`, which represents the pointer-to-member-function type.
- `#cir.method`, which represents a literal pointer-to-member-function value
that points to non-virtual member functions.
- `#cir.virtual_method`, which represents a literal pointer-to-member-function
value that points to virtual member functions.
- `cir.get_method_callee`, which resolves a pointer-to-member-function to a
function pointer as the callee.
See the new test at `clang/test/CIR/CIRGen/pointer-to-member-func.cpp` for how
these new CIR stuff works to support pointer-to-member-functions.
