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 :)

For example,
--
ddunbar@giles:Frontend$ clang -c backend-errors.c
fatal error: error in backend: Global variable 'a' has an invalid section specifier
      'I AM, not, legal': mach-o section specifier uses an unknown section type.
--
compare to:
--
ddunbar@giles:Frontend$ gcc -c backend-errors.c
/var/folders/DQ/DQ8GT3++HESEzT1obWBynE+++TI/-Tmp-//cc45w2pq.s:2:Expected comma after segment-name
/var/folders/DQ/DQ8GT3++HESEzT1obWBynE+++TI/-Tmp-//cc45w2pq.s:2:Rest of line ignored. 1st junk character valued 77 (M).
--

Yay!

I am not tied to my wording choice, we could also go with "uncoverable error"
for the prefix, or just leave it off entirely.

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.

Entity can now refer to declarations that are not visible outside the translation unit.
It is a wrapper of a pointer union, it's either a Decl* for declarations that don't
"cross" translation units, or an EntityImpl* which is associated with the specific "visible" Decl.

Included is a test case for handling fields across translation units.
