[lit] Make the gold plugin support testing work with a python3
interpreter. Seems that's a better path than pinning to python2.7.

Update ARM and x86 ArchHandler to match 64bits counterparts. NFC
Summary:
Define an explicit type for arch specific reference kind and use it in switch statement to make the compiler emit warnings if some case is not cover.
It will help to catch such errors when we add new mach-o reference kind.

Revert r229224: Make the 'llvm-lit' utility defend against a system where Python3
Apparantly python2.7 also doesn't work. Awesome.

[lit] Make the 'llvm-lit' utility defend against a system where Python3
is the default.
The lit.cfg files are not all valid Python3 and I've no idea if anyone
is really prepared to update them. The easiest way I know of to ensure
that this script uses Python 2 is to use 'python2.7' in the command. Mac
and Linux are definitely fine with this and I think other platforms will
be as well, but if anyone struggles with this set up and has better
ideas, let me know.

Revise the implementation logic of sized deallocation: Do not automatically generate weak definitions of the sized operator delete (in terms of unsized operator delete). Instead, provide the funcitonality via a new compiler flag, -fdef-sized-delete.
The current implementation causes link-time ODR violations when the delete symbols are exported into the dynamic table.

llvm-pdbdump: Only dump whitelisted global symbols.
Dumping the global scope contains a lot of very uninteresting

Furthermore, it dumps values unsorted, making it hard to read.
This patch dumps known interesting types only, and as a side
effect sorts the list by symbol type.
