893d475ba8 ARM: Use front-end specific target features "soft-float" and "soft-float-abi" to communicate FP mode to target; __SOFTFP__ is set correctly now.

7b245eda5e Targets: Allow CreateTargetInfo to mutate the target features. 
- In particular, it can claim features for itself instead of always passing them on to LLVM.
 - This allows using the target features as a generic mechanism for passing target specific options to the TargetInfo instance, which may need them for initializing preprocessor defines, etc.

acde99ea52 ARM: Fix predefines (__ARM_ARCH_..., __REGISTER_PREFIX).

   out. I'll fix it one day, I promise.

4f8a2e22c0 fix some cfstring related issues: 
1) -fwritable-string does affect the non-utf16 version of cfstrings
   just not the utf16 ones.
2) utf16 strings should always be marked constant, as the __TEXT segment
   is readonly.
3) The name of the global doesn't matter, remove it from TargetInfo.
4) Trust the asmprinter to drop cstrings into the right section, like llvmgcc does now.

This fixes rdar://7115750

30ba674391 fix a couple of problems with section attributes: 
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 :)
