[analyzer] Fix SVal/SymExpr/MemRegion class and enum names for consistency.
The purpose of these changes is to simplify introduction of definition files for the three hierarchies. 1. For every sub-class C of these classes, its kind in the relevant enumeration is changed to "CKind" (or C##Kind in preprocessor-ish terms), eg: MemRegionKind -> MemRegionValKind RegionValueKind -> SymbolRegionValueKind CastSymbolKind -> SymbolCastKind SymIntKind -> SymIntExprKind 2. MemSpaceRegion used to be inconsistently used as both an abstract base and a particular region. This region class is now an abstract base and no longer occupies GenericMemSpaceRegionKind. Instead, a new class, CodeSpaceRegion, is introduced for handling the unique use case for MemSpaceRegion as "the generic memory space" (when it represents a memory space that holds all executable code). 3. BEG_ prefixes in memory region kind ranges are renamed to BEGIN_ for consisitency with symbol kind ranges. 4. FunctionTextRegion and BlockTextRegion are renamed to FunctionCodeRegion and BlockCodeRegion, respectively. The term 'code' is less jargony than 'text' and we already refer to BlockTextRegion as a 'code region' in BlockDataRegion. Differential Revision: http://reviews.llvm.org/D16062 llvm-svn: 257598
