[PATCH] D29330: Replace MergeOutputSection with synthetic input section MergeSection.

[Rafael Ávila de Espíndola via Phabricator via llvm-commits]

rafael created this revision.

This is a fresh start on the review of https://reviews.llvm.org/D27415. It is George patch with some simplifications.

I can be simplified further by not setting Entsize, but that is probably better done is a followup patch.

This should allow some cleanup is the linker script code now that every output section command maps to just one output section.
