Ted Kremenek 8bafa2cf9f 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).

Ted Kremenek 6ed79f0c13 Use a union instead of a bunch of magic casts to implement a variant. This removes the type-punning errors for DeclGroup.

Devang Patel 597e70876e Now Attributes are divided in three groups
- return attributes - inreg, zext and sext
- parameter attributes
- function attributes - nounwind, readonly, readnone, noreturn

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

Chris Lattner c88a23e8d7 Fix the rest of rdar://6243860 hopefully. This requires changing FileIDInfo
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.

Chris Lattner e744d32b72 emulate a bit of GCC path lookup weirdness: if a system
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

instead of:

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

This is part of rdar://6243860.

degraded to asserts for the time being).

- readonly and readwrite are mutually exclusive.
 - assign, copy, and retain are mutually exclusive.
 - copy and retain are invalid on non-object types.
 - Warn about using default 'assign' property on object types
   (attempting to follow gcc behavior).

Ted Kremenek 34bfd8a490 Fixed logic error in BasicConstraintManager pointed out by Zhongxing Xu.
For checking if a symbol >= value, we need to check if symbol == value || symbol
> value. When checking symbol > value and we know that symbol != value, the path
is infeasible only if value == maximum integer.

For checking if a symbol <= value, we need to check if symbol == value || symbol
< value. When checking symbol < value and we know that symbol != value, the path
is infeasible only if value == minimum integer.

Updated test case exercising this logic: we only prune paths if the values are
unsigned.
