New Revision: 49848

URL: http://llvm.org/viewvc/llvm-project?rev=49848&view=rev
Log:
Run SimplifyLibCalls near the beginning, not at
the end.  It is now run at the same moment as in
llvm-gcc.  Also, run StripDeadPrototypes at the
end, just before running DeadTypeElimination.
This may be useful when doing LTO.  Note that
llvm-gcc runs StripDeadPrototypes but not
DeadTypeElimination.
