[legalize-types] Remove stale entries from SoftenedFloats. Summary: When replacing a SDValue, we should remove the replaced value from SoftenedFloats (and possibly the other maps as well?). When we revisit a Node because it needs analyzing again, we have to remove all result values from SoftenedFloats (and possibly other maps?). This fixes the fp128 test failures with expensive checks for X86. I think we probably should also remove the values from the other maps (PromotedIntegers and so on), let me know what you think.

[X86] Part 2 to fix x86-64 fp128 calling convention. Part 1 was submitted in http://reviews.llvm.org/D15134. Changes in this part: * X86RegisterInfo.td, X86RecognizableInstr.cpp: Add FR128 register class. * X86CallingConv.td: Pass f128 values in XMM registers or on stack. * X86InstrCompiler.td, X86InstrInfo.td, X86InstrSSE.td: Add instruction selection patterns for f128. * X86ISelLowering.cpp: When target has MMX registers, configure MVT::f128 in FR128RegClass, with TypeSoftenFloat action, and custom actions for some opcodes. Add missed cases of MVT::f128 in places that handle f32, f64, or vector types. Add TODO comment to support f128 type in inline assembly code. * SelectionDAGBuilder.cpp: Fix infinite loop when f128 type can have VT == TLI.getTypeToTransformTo(Ctx, VT). * Add unit tests for x86-64 fp128 type.
