register names in the standalone assembler llvm-mc.

Registers such as $A1 can represent either a 32 or
64 bit register based on the instruction using it.
In addition, based on the abi, $T0 can represent different
32 bit registers.


The problem is resolved by the Mips specific AsmParser 
td definitions changing to work together. Many cases of
RegisterClass parameters are now RegisterOperand.

Providing a data formatter for libc++ std::wstring
In the process, refactoring the std::string data formatter to be written in C++ so that commonalities between the two can be exploited
Also, providing a new API on the ValueObject to navigate a hierarchy by index-path
Lastly, an appropriate test case is included

When tryEvict() is looking for a cheaper register in the allocation
order, skip the tail of too expensive registers when possible.

llvm-svn: 172281

Remember the minimum cost of the registers in an allocation order and
the number of registers at the end of the allocation order that have the
same cost per use.

This information can be used to limit the search space for
RAGreedy::tryEvict() when looking for a cheaper register.

Previously, -Wunused-comparison ignored comparisons in both macro bodies and
macro arguments, but we would still emit a -Wunused-value warning for either.
Now we correctly emit -Wunused-comparison for expressions in macro arguments.

Also, add isMacroBodyExpansion to SourceManager, to go along with
isMacroArgExpansion.

The MCAsmParser interface defines ParseIdentifier is public. There's no reason
whatsoever for AsmParser (which implements the MCAsmParser interface) to hide
this method.

This is all part of a bigger scheme. Several asm parsing "extensions" use the
main parser properly through the MCAsmParser interface. However,
GenericAsmParser has much more exclusive access and uses implementation details
from the concrete implementation - AsmParser, in which it is also declared as
a friend. This makes for overly coupled code, and even makes it hard to split
GenericAsmParser into a separate file. There's no reason why GenericAsmParser
shouldn't be able to access AsmParser through an abstract interface, as long
as it's actually registered as an extension.

Fixed an issue with the auto loading of script resources in debug info files. Any platform can add support for this, and on MacOSX we allow dSYM files to contain python modules that get automatically loaded when a dSYM file is associated with an executable or shared library. 

The modifications will now:
- Let the module locate the symbol file naturally instead of using a function that only works in certain cases. This helps us to locate the script resources as long as the dSYM file can be found.
- Don't try and do any of this if the script interpreter has scripting disabled.
- Allow more than one scripting resource to be found in a symbol file by returning the list
- Load the scripting resources when a symbol file is added via the "target symbols add" command.
- Be smarter about matching the dSYM mach-o file to an existing executable in the target images by stripping extensions on the symfile basname if needed.

The end goal is having just a single place (and a single lookup table) for

Specifically:
1. Added a missing new line when we emit a debug message saying that we are marking a global variable as constant.
2. Added debug messages that describe what is occuring when GlobalOpt is evaluating a block/function.
3. Added a debug message that says what specific constructor is being evaluated.

This fixes some of the cycles between libCodeGen and libSelectionDAG. It's still
a complete mess but as long as the edges consist of virtual call it doesn't
cause breakage. BasicTTI did static calls and thus broke some build
configurations.

this makes sense.
