Changed all of our synthesized "___clang" functions, types and variables
that get used in expressions over to have a prefix of "$_lldb". Now when we
do name lookups we can easily switch off of the first '$' character to know
if we should look through only our internal (when first char is '$') stuff,
or when we should look through program variables, functions and types.
Converted all of the clang expression code over to using "const ConstString&"
values for names instead of "const char *" since there were many places that
were converting the "const char *" names into ConstString names and them
throwing them away. We now avoid making a lot of ConstString conversions and
benefit from the quick comparisons in a few extra spots.
Converted a lot of code from LLVM coding conventions into LLDB coding
conventions.

- Sema is now exported (and there was much rejoicing.)
- Storage classes are now centrally defined.
Also fixed some bugs that the new LLVM picked up.

- If you put a semicolon at the end of an expression,
this no longer causes the expression parser to
error out. This was a two-part fix: first,
ClangExpressionDeclMap::Materialize now handles
an empty struct (such as when there is no return
value); second, ASTResultSynthesizer walks backward
from the end of the ASTs until it reaches something
that's not a NullStmt.
- ClangExpressionVariable now properly byte-swaps when
printing itself.
- ClangUtilityFunction now cleans up after itself when
it's done compiling itself.
- Utility functions can now use external functions just
like user expressions.
- If you end your expression with a statement that does
not return a value, the expression now runs correctly
anyway.
Also, added the beginnings of an Objective-C object
validator function, which is neither installed nor used
as yet.

certain functions from being resolved correctly.
Some functions (particularly varargs functions)
are BitCast before being called, and the problem
was that a CallInst where getCalledValue()
returned a BitCast ConstantExpr was not being
relocated at all.
This problem should now be resolved for the case
of BitCast.

expressions. If an expression dereferences an
invalid pointer, there will still be a crash -
just now the crash will be in the function
___clang_valid_pointer_check().
llvm-svn: 112785
expressions. Values used by the expression are
checked by validation functions which cause the
program to crash if the values are unsafe.
Major changes:
- Added IRDynamicChecks.[ch], which contains the
core code related to this feature
- Modified CommandObjectExpression to install the
validator functions into the target process.
- Added an accessor to Process that gets/sets the
helper functions
