Enable -mergefunc-use-aliases
If the Rust LLVM fork is used, enable the -mergefunc-use-aliases flag, which will create aliases for merged functions, rather than inserting a call from one to the other. A number of codegen tests needed to be adjusted, because functions that previously fell below the thunk limit are now being merged. Merging is prevented either using -C no-prepopulate-passes, or by making the functions non-identical. I expect that this is going to break something, somewhere, because it isn't able to deal with aliases properly, but we won't find out until we try :) This fixes #52651.
