This is alternative to https://reviews.llvm.org/D44622 and https://reviews.llvm.org/D44601.

This fixes PR36367 which is about segfault when --emit-relocs is
used together with .eh_frame sections which happens because
of reordering of regular and .rel[a] sections.

In this patch, 2 iterations over input sections are done, first for
regular section and second for .rel[a] sections.
