New Revision: 53236

URL: http://llvm.org/viewvc/llvm-project?rev=53236&view=rev
Log:
Global variables beginning with \01 have special meaning on Darwin, so we need to remove
the name prefix when we change them from internal to external.  This allows bugpointing
of codegen miscompilations to work more reliably on Darwin.
