Support fuzzy parsing MS line-oriented __asm's that originate from a macro (a case where we can't obtain source line info). As the test case indicates, we don't currently support line-oriented asm statements that mix file/macro body tokens.

- Add support for fuzzy parsing line-oriented __asm's (yuck).
- Change handling of __w64 to a built-in macro.

Fix codegen of struct { short a[3]; int b:15; }.

struct {
  char a[3];
  unsigned char b:1;
};

Fix PR1990.

Minor cleanup from yesterday's -fms-extension commit. Move __int* MS keywords to predefined macros. This removes some of the MS-madness from Parser::ParseDeclarationSpecifiers().

Minor cleanups with generating nodes for NULL-pointer dereferences.

Modified the driver to pass the Diagnostic object to GRConstants.

-fms-extensions of course.

Fixed bug in RemoveDeadBindings by implementing a simple "mark-and-sweep"
cleaner over the bindings, starting from the Decls and block-level expressions
that are considered "live" by the Liveness analysis.

Fixed bug in isa<> implementation for class LValue.

Added "VisitDeclRefExpr" to GRConstants so that we explicitly bind the current
value of variable to the Block-level Expression (i.e., when the DeclRefExpr is
at the CFGBlock level).

Implement -fms-extensions. This allows us to fuzzy parse non-standard MS constructs used in "windows.h".

llvm-svn: 46838

as the initializers for DeclStmts were not being registered as being
live at the start of the DeclStmt.

Fixed insidious bug in handling dereferences.

code structure is more suitable for additional symbolic analysis.

explicitly document that return statement argument does not necessarily follow the result type of the function.  Add testcase.

"if(x)". On the true branch we know the value is != 0, and on the false branch
we know it is 0.
