Denis Protivensky 9e4f87b329 [Mips] Fix createMipsRelocationHandler specialization (take 2)
Misread buildbot's log.
Both gcc and clang compile this fine.

Original fix reason:
gcc allows template specializations only in the same namespace
where template has been declared.

Denis Protivensky 2b5539651b [lld] Correct forming of ARM/Thumb atoms
Symbols addressing Thumb code have zero bit set in st_value to distinguish them from ARM instructions.
This caused wrong atoms' forming because of offset of one byte brought in by that corrected st_value.

Fixed reading of st_value & st_value-related things in ARMELFFile while forming atoms.
Symbol table generation is also fixed for Thumb atoms.

Rui Ueyama 9af09d758a Fix incorrect atom ordinal.
Anonymous atoms created there were getting wrong atom ordinal.
LayoutAfter references take precedence over atom ordinals, so
the bug was not visible, though.

Rui Ueyama 87d10ef325 Use parallel_sort in the LayoutPass.
Time to link lld using lld improved from 5.7s to 5.4s on Windows.
It's not a significant improvement but not bad for one-line change.

This patch includes a bug fix for Parallel.h as the original code
uses operator< instead of a compare function there.

Simon Atanasyan 0712650742 [Mips] Teach LLD to recognize one more MIPS target triple - mips64el
This is initial patch to support MIPS64 object files linking.
The patch just makes some classes more generalized, and rejects
attempts to interlinking O32 and N64 ABI object files.

I try to reuse the current MIPS target related classes as much as
possible because O32 and N64 MIPS ABI are tightly related and share
almost the same set of relocations, GOT, flags etc.

Rui Ueyama e6556a9cea Fix --start-group/end-group.
We used to manage the state whether we are in a group or not
using a counter. The counter is incremented by one if we jump from
end-group to start-group, and decremented by one if we don't.
The counter was assumed to be either zero or one, but obviously it
could be negative (if there's a group which is not repeated at all).
This is a fix for that issue.
