Jordy Rose b891bd8a3c [analyzer] When performing a binary operation on symbolic operands, we convert the symbol values to a common type. But in a relational operation, the result is an 'int' or 'bool', which may not be the appropriate type to convert the operands to. In these cases, use the left-hand operand's type as the conversion type.
There's no associated test for this because fully-constrained symbolic values are evaluated ahead of time in normal expressions. This can only come up in checker-constructed expressions (like the ones in an upcoming patch to CStringChecker).

Zhanyong Wan 5ad574c096 Improves the coding style in SValBuilder. This patch:
- renames evalCastNL and evalCastL to evalCastFromNonLoc and
  evalCastFromLoc (avoid abbreviations that aren't well known).

- makes all function parameter names start with a lower case letter
  for consistency and distinction from member variables.

- avoids abbreviations in function parameter names.

Ted Kremenek f8cbac4b91 Split 'include/clang/StaticAnalyzer' into 'include/clang/StaticAnalyzer/Core' and 'include/clang/StaticAnalyzer/Checkers'.
This layout matches lib/StaticAnalyzer, which corresponds to two StaticAnalyzer libraries.

Argyrios Kyrtzidis fa0734ec4f [analyzer] Move the files in lib/StaticAnalyzer to lib/StaticAnalyzer/Core.
Eventually there will also be a lib/StaticAnalyzer/Frontend that will handle initialization and checker registration.
Yet another library to avoid cyclic dependencies between Core and Checkers.
