The one annoying thing about this patch is that the MCSymbolExpr isn't
expressive enough to represent ha16(label1-label2) which we need on
PowerPC. I have a terrible hack in the meantime, but this will have
to be revisited at some point.

Just like functions can have a basename and a mangled/demangled name, variable
...
can too. So now the lldb_private::Variable class has support for this.
Variables now have support for having a basename ("i"), and a mangled name
("_ZN12_GLOBAL__N_11iE"), and a demangled name ("(anonymous namespace)::i").
Nowwhen searching for a variable by name, users might enter the fully qualified
name, or just the basename. So new test functions were added to the Variable
and Mangled classes as:
bool NameMatches (const ConstString &name);
bool NameMatches (const RegularExpression ®ex);
I also modified "ClangExpressionDeclMap::FindVariableInScope" to also search
for global variables that are not in the current file scope by first starting
with the current module, then moving on to all modules.
Fixed an issue in the DWARF parser that could cause a varaible to get parsed
more than once. Now, once we have parsed a VariableSP for a DIE, we cache
the result even if a variable wasn't made so we don't do any re-parsing. Some
DW_TAG_variable DIEs don't have locations, or are missing vital info that
stops a debugger from being able to display anything for it, we parse a NULL
variable shared pointer for these DIEs so we don't keep trying to reparse it.
