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.

a7d0231b66 clang -cc1: Rename -mcpu to -target-cpu to match other target options and not alias driver/backend option.

24c7f5efc5 Add -dwarf-debug-flags, which provides a way to embed the cc1 level options used 
to compile a translation unit into the debug info for that file.
 - Used by parts of Darwin build process to check compiler flags, etc.
 - <rdar://problem/7256886> clang does not emit AT_APPLE_flags

13c88c7269 implement PR5654: add -fassume-sane-operator-new, which is enabled by default, and adds the malloc attribute to the global function new() and to the overloaded new operators. 
feel free to chage the name to this lengthy argument

d954638f02 Implement runtime checks for undefined behavior. WIP. 
This implements a new flag -fcatch-undefined-behavior.  The flag turns
on additional runtime checks for:

  T a[I];

  a[i]    abort when i < 0 or i >= I.

Future stuff includes shifts by >= bitwidth amounts.

eadc7c3537 Make using '-fshort-enums' an error until it is actually implemented (changes the ABI, so it is dangerous to not error out if we don't support it). Fixes <rdar://problem/7461006>.

a74f8ff15c Add CodeGenOptions::{SoftFloat,FloatABI}, and update the all the (far too many) places to use this instead of using the backend -soft-float and -float-abi= options.

a1b02a2380 Move LLVM backend options to explicit clang-cc / clang -cc1 options, which we then manually pass to the command line library; eventually the latter grossness should be fixed by a real API when creating the target machine.

fffd18167d Driver: Switch to using explicit {getLast,has}ArgNoClaim functions instead of taking a Claim argument. 
- Most driver code always claims, and bool arguments don't play nice with the overloads.

As per Fariborz's suggestion, committed now but can be reverted later if the used flag is problematic for Apple.

e13ada6a3b Add clang -mcpu=native support, patch by Roman Divacky, varioustweaks by me. 
- We still need support for detecting the target features, since the name
   doesn't actually do a good job of decribing what the CPU supports (for LLVM).
