[PATCH] D42542: Improve LMARegion handling

[Rafael Avila de Espindola via Phabricator via llvm-commits]

This fixes the crash reported at PR36083.

The issue is that we were trying to put all the sections in the same PT_LOAD and crashing trying to write past the end of the file.

This also adds accounting for used space in LMARegion, without it all 3 PT_LOADs would have the same physical address.
