The AllocaRegion did not have the superRegion (based on LocationContext)
as part of it's hash. As a consequence, the AllocaRegions from
different frames were uniqued to be the same region.

In preparation for the FileCheck functionality change which will allow using
a variable later on the same line.
No functionality change.

initialization, don't rebuild it. Remove a couple of hacks which were trying to
work around this. Fix the special case for one-argument CXXConstructExprs to
not apply if the one argument is a default argument.

The bug can be triggered when we require LoopInfo analysis ahead of DominatorTree construction in a Module Pass. The cause is that the LoopInfo analysis itself also invokes DominatorTree construction, therefore, when PassManager schedules LoopInfo, it will add DominatorTree first. Then after that, when the PassManger turns to schedule DominatorTree invoked by the above ModulePass, it finds there is already a DominatorTree, so it delete the redundant one. However, somehow it still try to access that pass pointer after free as code pasted below, which results in segment fault.

Adding CXX_SUPPORTS_COVERED_SWITCH_DEFAULT_FLAG
C_SUPPORTS_COVERED_SWITCH_DEFAULT_FLAG
This is to handle the wackiness on a Mac host where cmake detects:
CMAKE_CXX_COMPILER == "/usr/bin/c++"
CMAKE_C_COMPILER == "/usr/bin/gcc"

- Widespread trailing space removal
- A dash of OCD spacing to block align enums
- joined a line that probably needed 80 cols a while back

to support it. Original patch with the parsing and plumbing by the PaX team and
Roman Divacky. I added the bits in MCDwarf.cpp and the test.

Necessary to give disassembler users (like darwin's otool) a possibility to
dlopen libLTO and still initialize the required LLVM bits. This used to go
through libMCDisassembler but that's a gross layering violation, the MC layer
can't pull in functions from the targets. Adding a function to libLTO is a bit
of a hack but not worse than exposing other disassembler bits from libLTO.
Fixes PR14362.

The last remaining bit is "bcl 20, 31, AnonSymbol", which I couldn't find the
instruction definition for. Only whitespace changes in assembly output.
