The following have been updated in this patch:

- trailing whitespace removed
- soft-float.ll tests is now correctly specified, the test cases have been simplified, added tests for fp128, and file was renamed from softfloat.ll
- adjusted the test cases in 32abi.ll and 62abi.ll to include testing for software floating point
- Adjusted behavior for fp128/quad floats so that the compiler-rt function calls (__addtf3 and so forth) are used for all floating point operations, including fp128, when soft-float option is enabled (before calls to _Q_add was used for fp128/quad floats when softfloat was enabled)
