The token stream was not getting properly reset when leaving
ParseLexedMethodDef in some error cases. In the testcase, that caused later
accesses to the token stream to touch memory which had been freed as we
finished parsing the class definition. Major hat-tip to AddressSanitizer for
helping pinpoint the use-after-free, including the allocation and deallocation
points:

to operate "as if" in a certain working directory.
 - For now, we just implement this by changing the actual working directory, but
   eventually we would want to handle this transparently. This is useful to
   avoid an extra exec() pair in some situations, and will be something we would
   want to support for more flexibility in using the Clang libraries.

is cast to a boolean.  An exception has been made for string literals in
logical expressions to allow the common case of use in assert statements.

bool x;
x = "hi";  // Warn here
void foo(bool x);
foo("hi");  // Warn here
assert(0 && "error");
assert("error);  // Warn here

Move immutable map canonization out of the removeDeadBindings loop (via using ImmutableMapRef). Gives ~2% speedup.

declaration. Perhaps FunctionDecl::isInlined() is poorly named. Fixes

constructor template. Fixes PR10457.

llvm-svn: 140350

[microsoft] Fix a bug in -fdelayed-template-parsing mode where we were not reentering the delayed function context correctly. The problem was that all template params were reintroduced inside the same scope. So if we had a situation where we had 2 template params with the same name at different scope then clang would generate an error about ambiguous name.

The solution is to create a new ParseScope(Scope::TemplateParamScope) for each template scope that we want to reenter. (from the outmost to the innermost scope)

This fixes some errors when parsing MFC code with clang.

This moves the existing code for CPATH into the driver and adds the environment lookup and path splitting there.
The paths are then passed down to cc1 with -I options (CPATH), added after the normal user-specified include dirs.
Language specific paths are passed via -LANG-isystem and the actual filtering is performed in the frontend.

I tried to match GCC's behavior as close as possible

Fixes PR8971.

It's not valid to remove filters from landingpad instructions, even if we catch
the type. The metadata won't be set up correctly.

generation when we're dealing with an implicitly-defined copy or move
constructor. And, actually set the implicitly-defined bit for
implicitly-defined constructors and destructors. Should fix self-host.

ST->scanReachableSymbols() is creating a SubRegionMap (SRM) on every call since one SRM is created in each ScanReachableSymbols instance. Creating the object just once and calling only scan inside the loop gives ~ 14% speed up of the StaticAnalyzer run (Release+Asserts). 

Pull out the declaration of the ScanReachableSymbols so that it can be used directly. Document ProgramState::scanReachableSymbols() methods.
