Jordan Rose 2be02a7848 [analyzer] Shitfing a constant value by its bit width is undefined.
Citation: C++11 [expr.shift]p1 (and the equivalent text in C11).

This fixes PR18073, but the right thing to do (as noted in the FIXME) is to
have a real checker for too-large shifts.

Jordan Rose 21580c2f92 [analyzer] Disallow creation of int vals with explicit bit width / signedness.
All clients of BasicValueFactory should be using QualTypes instead, and
indeed it seems they are. This caught the (fortunately harmless) bug
fixed in the previous commit.

No intended functionality change.

Benjamin Kramer 1ea8e092be Drop the ASTContext.h include from Stmt.h and fix up transitive users.
This required moving the ctors for IntegerLiteral and FloatingLiteral out of
line which shouldn't change anything as they are usually called through Create
methods that are already out of line.

ASTContext::Deallocate has been a nop for a long time, drop it from ASTVector
and make it independent from ASTContext.h

Pass the StorageAllocator directly to AccessedEntity so it doesn't need to
have a definition of ASTContext around.

Ted Kremenek 5ef32dbf2a Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at.

Ted Kremenek 8df44b2632 [analyzer] Introduce new MemRegion, "TypedValueRegion", so that we can separate TypedRegions that implement getValueType() from those that don't.

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.
