resolving an overloaded function reference within an initializer list.
Previously we would try to resolve the overloaded function reference without
first stripping off the InitListExpr wrapper.

This simplifies the usage and implementation of ELFObjectFile by using ELFType
to replace:

<endianness target_endianness, std::size_t max_alignment, bool is64Bits>

This does complicate the base ELF types as they must now use template template
parameters to partially specialize for the 32 and 64bit cases. However these
are only defined once.

with function definitions.

We really should remove Parser::isDeclarationAfterDeclarator entirely, since
it's meaningless in C++11 (an open brace could be either a function definition
or an initializer, which is what it's trying to differentiate between). The
other caller of it happens to be correct right now...

attributes appertain to a declaration, even though they would be much more
naturally modelled as appertaining to a function type. Previously, we would
try to distribute them from the declarator to the function type, then
reject them for being at an incorrect location. Now, we just distribute them
as far as the declarator; the existing attribute handling code can actually
apply them there just fine.

Separated the "expr --unwind-on-error" behavior into two parts, actual errors (i.e. crashes) which continue to be
controlled by the --unwind-on-error flag, and --ignore-breakpoint which separately controls behavior when a called
function hits a breakpoint.  For breakpoints, we don't unwind, we either stop, or ignore the breakpoint, which makes
more sense.  
Also make both these behaviors globally settable through "settings set".
Also handle the case where a breakpoint command calls code that ends up re-hitting the breakpoint.  We were recursing
and crashing.  Now we just stop without calling the second command.

simply use the getParser method from MCAsmParserExtension, working through the
MCAsmParser interface. There's no longer a need to overload that method to
cast it to the concrete AsmParser.

This finally allows AsmParser to no longer list GenericAsmParser as a friend.
All member vars directly accessed by GenericAsmParser have been properly
encapsulated and exposed through the MCAsmParser interface. This reduces the
coupling between AsmParser and GenericAsmParser.
