Sebastian Neubauer 2b08f6af62 [AMDGPU] Improve register computation for indirect calls ...

First, collect the register usage in each function, then apply the
maximum register usage of all functions to functions with indirect
calls.

This is more accurate than guessing the maximum register usage without
looking at the actual usage.

As before, assume that indirect calls will hit a function in the
current module.
