Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right; many more remain.

- Change TargetData string to match llvm-gcc.
- Some -target-abi support for 'apcs-gnu', most importantly the alignment of double and long long changes.

avoid emitting a warning on "someptr > 0". This is obviously questionable (they
could use != instead) but is reasonable, and the warning "ordered comparison
between pointer and integer" didn't make a ton of sense because 0 is a valid
null pointer constant.
Just silence the warning in this case, it is unlikely to indicate a bug.

where sizeof(short) == sizeof(int). Move UsualArithmeticConversionsType
out of Sema, since it was only there as a historical artifact. Patch by

declarations (and not function pointers). This is consistent with GCC. Accepting
this attribute on function pointers means that the attribute should be treated
as a type qualifier, which apparently is not what GCC does. We obviously can
change this later should we desire to enhance the 'malloc' attribute in this
way.

Fixes PR4704 problems
Addresses Eli's patch feedback re: ugly cast code
Updates all postfix operators to remove ParenListExprs. While this is awful,
no better solution (say, in the parser) is obvious to me. Better solutions
welcome.

1. Passing something that isn't a string used to cause:
"argument to annotate attribute was not a string literal"
make it say "section attribute" instead.
2. Fix the location of the above message to point to the
bad argument instead of the section token.
3. Implement rdar://4341926, by diagnosing invalid section
specifiers in the frontend rather than letting them slip all
the way to the assembler (a QoI win).
An example of #3 is that we used to produce something like this:
/var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Expected comma after segment-name
/var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Rest of line ignored. 1st junk character valued 46 (.).
Daniel improved clang to use llvm_report_error, so now we got:
$ clang t.c -c
fatal error: error in backend: Global variable 'x' has an invalid section specifier 'sadf': mach-o section specifier
requires a segment and section separated by a comma.
with no loc info. Now we get:
$ clang t.c -fsyntax-only
t.c:4:30: error: argument to 'section' attribute is not valid for this target: mach-o section specifier requires a segment
and section separated by a comma
int x __attribute__((section("sadf")));
^
which is nice :)

In addition to being defined by the AltiVec PIM, this is also the vector
initializer syntax used by OpenCL, so that vector literals are compatible
with macro arguments.
