Enhance dead store checker to not flag preincrements to dead variables where the preincrement is a subexpression, e.g. foo(++x);  This can cause false negatives, but will remove a whole class of false positives.

Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl.
Cleans up the code a bit and better reflects that Decl class structure.

Note: One day, we should consider moving the actual diags to ObjCQualifiedIdTypesAreCompatible(), since it has more information on the actual problem. GCC currently emits slightly more instructive errors for some cases involving protocols. I added a FIXME to the code.

on non-float types.

 - Follows the MSVC (original) implementation, including support of
   pack(show) (useful for testing).
 - Implements support for named pack records which gcc seems to
   ignore (or implements incorrectly).
 - Not currently wired to anything, only functionality change is the
   type checking of the pragma.

Add "-analyze-headers" option to scan-build that passes the option -analyzer-opt-analyze-headers to clang.

 - Currently still lives in CGCall.cpp but is intended to be the
   target specific place for hooking ABI information.
 - Select ABIInfo to use based on Target's prefix and pointer width.

No functionality change.

When the static type on the Decl side is a subclass of DeclContext the compiler will use a "inlinable" static_cast, instead of always using an out-of-line function call.

Note, though, that the isa<> check still uses an out-of-line function call.

wraps comments in <i> tags.  Extend rewrite tokens to support

it is probably the most complex version of 'cat' ever invented.

were setting a kind and then forming it.  This is just a minor API cleanup,

unterminated.

keep comment mode, instead of returning false.  This matches SkipWhitespace.

even whitespace, as tokens from the file.  This is enabled with
L->SetKeepWhitespaceMode(true) on a raw lexer.  In this mode, you too
can use clang as a really complex version of 'cat' with code like this:

  Lexer RawLex(SourceLocation::getFileLoc(SM.getMainFileID(), 0),
               PP.getLangOptions(), File.first, File.second);
  
  RawLex.SetKeepWhitespaceMode(true);
  
  Token RawTok;
  RawLex.LexFromRawLexer(RawTok);
  while (RawTok.isNot(tok::eof)) {
    std::cout << PP.getSpelling(RawTok);
    RawLex.LexFromRawLexer(RawTok);
  }

This will emit exactly the input file, with no canonicalization or other
translation.  Realistic clients actually do something with the tokens of
course :)

same we we do an unterminated string or character literal.  This makes
it so we can guarantee that the lexer never calls into the 
preprocessor (which would be suicide for a raw lexer).

llvm-svn: 57395

llvm-svn: 57394

using LexRawToken, create one and use LexFromRawLexer.  This avoids
twiddling the RawLexer flag around and simplifies some code (even 
speeding raw lexing up a tiny bit).

This change also improves the token paster to use a Lexer on the stack
instead of new/deleting it.
