Internally store the body of a BlockExpr using a Stmt* instead of a CompoundStmt*, and use the getBody() method to do the appropriate checking.  This both removes the type-punning warnings in Expr.cpp and also makes BlockExpr have more consistency checks against modifications to its body (via StmtIterator).

Use a union instead of a bunch of magic casts to implement a variant.  This removes the type-punning errors for DeclGroup.

Return attributes use 0 as the index.
Function attributes use ~0U as the index.

This patch requires corresponding changes in llvm-gcc and clang.

to whether the fileid is a 'extern c system header' in addition to whether it
is a system header, most of this is spreading plumbing around.  Once we have that,
PPLexerChange bases its "file enter/exit" notifications to PPCallbacks to
base the system header state on FileIDInfo instead of HeaderSearch.  Finally,
in Preprocessor::HandleIncludeDirective, mirror logic in GCC: the system headerness
of a file being entered can be set due to the #includer or the #includee.

directory is shadowed by a user directory in the lookup
path, ignore the user directory not the system one.  Not
doing this can affect file lookup and the "is a system
header" bit on locations.  For example:
  clang -v -I/usr/include inc.c -E | & grep /usr/inc
now prints:

# 1 "/usr/include/i386/_types.h" 1 3 4
# 37 "/usr/include/i386/_types.h" 3 4
# 70 "/usr/include/i386/_types.h" 3 4

# 1 "/usr/include/i386/_types.h" 1
