Rejected 169195. As Duncan commented, bitcasting to proper type is wrong approach. We need to insert some valid TRANCATE node here.

Add a new helper function, AddOpt(F1, F1, Opt), as part of PR13574.  No
functional change intended.  Patch by Weiming Zhao <weimingz@codeaurora.org>.

Tidy up a few more uses of MF.getFunction()->getName().

Based on CR feedback from r162301 and Craig Topper's refactoring in r162347
here are a few other places that could use the same API (& in one instance drop
a Function.h dependency).

Add a few float shrinking optimizations to SimplifyLibCalls.  Unsafe
optimizations are guarded by the -enable-double-float-shrink LLVM option.

[ms-inline asm] Avoid a false positive assertion

Assertion failed: (Start.isValid() == End.isValid() && "Start and end should 
either both be valid or both be invalid!")

when parsing inline asm.  SMLoc assumes that the first char * in the source is
invalid.  However, when parsing an inline asm the mnemonic is at this location.
I don't want to change SMLoc, so use a trivial workaround.

MCInstFragment constructor should take by-reference MCInst.

The MCInst is immediately passed to the copy-constructor for local
storage, so there's no need for the parameter itself to be by-value.

Print out the location of expanded multiclass defs in TableGen errors.

When reporting an error for a defm, we would previously only report the
location of the outer defm, which is not always where the error is.

Now we also print the location of the expanded multiclass defs:

lib/Target/X86/X86InstrSSE.td:2902:12: error: foo
  defm ADD : basic_sse12_fp_binop_s<0x58, "add", fadd, SSE_ALU_ITINS_S>,

  defm PD : sse12_fp_packed<opc, !strconcat(OpcodeStr, "pd"), OpNode, VR128,

Make function loadImmediate a member of MipsSEInstrInfo and change it to return
the temporary register that was used to load the immediate. Currently, it always
returns register $at, but this will change if, in the future, we decide to use 
another register.

Simplify the computeOperandLatency API.

The logic for recomputing latency based on a ScheduleDAG edge was
shady. This bypasses the problem by requiring the client to provide
operand indices. This ensures consistent use of the machine model's
API.
