Tom Care 82b2a1dada Improved the handling of blocks and block variables in PseudoConstantAnalysis 
- Removed the assumption that __block vars are all non-constant
- Simplified some repetitive code in RunAnalysis
- Added block walking support
- Code/comments cleanup
- Separated out test for block pseudoconstants

John McCall 8302463dc6 Split out a header to hold APIs meant for the Sema implementation from Sema.h. 
Clients of Sema don't need to know (for example) the list of diagnostics we
support.

Douglas Gregor 0de55cecb2 When combining the code-completion results from Sema long with the 
code-completion results cached by ASTUnit, sort the resulting result
set. This makes testing far, far easier, so this commit also includes
tests for the previous few fixes.

Douglas Gregor f11096c99c Initialize the translation-unit scope before lexing the first 
token. The first token might be something that ends up triggering code
completion, which in turn requires a valid Scope. Test case forthcoming.

Douglas Gregor ea7363732a Add a code-completion context for "natural language" completions, so 
that ASTUnit knows not to try to provide completions there.

Douglas Gregor 115837041e Introduce a preprocessor code-completion hook for contexts where we 
expect "natural" language and should not provide any completions,
e.g., comments, string literals, #error.

Douglas Gregor 4d755e86b4 Give a slight preference to functions returning "void" when we're 
performing code completion at the statement level (rather than in an
arbitrary expression).

Douglas Gregor 45140a9040 In code-completion contexts where both types and other values are 
present, prefer values to types, since it's more common to compute
with values than it is to declare new entities or perform type
casts. So, tweak the ranking of types vs. other declarations and
constants accordingly.

John McCall 24d189484b When trying to resolve the address of an overloaded expression, 
only form pointers-to-member if the expression has the appropriate
form.  This avoids assertions later on on invalid code, but also
allows us to properly resolve mixed-staticity overloads.

Instead of implementing -isystem, I accidentally implemented this cousin.  Next
up is to implement -isystem right.

Tom Care a460311710 Improvements to IdempotentOperationChecker and its use of PseudoConstantAnalysis 
- Added wasReferenced function to PseudoConstantAnalysis to determine if a variable was ever referenced in a function (outside of a self-assignment)
- BlockDeclRefExpr referenced variables are now explicitly added to the non-constant list
- Remove unnecessary ignore of implicit casts
- Generalized parameter self-assign detection to detect deliberate self-assigns of variables to avoid unused variable warnings
- Updated test cases with deliberate self-assignments
- Fixed bug with C++ references and pseudoconstants
- Added test case for C++ references and pseudoconstants
