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.

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.

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
