Patch by Konstantin Schwarz! If both the MemRegion and LMARegion are set for an output section in a linker script, we should only increase the LMARegion if it is different from the MemRegion. Otherwise, we reserve the memory twice. Differential revision: https://reviews.llvm.org/D50065 llvm-svn: 338684
