Use COPY for fast-isel bitconvert, but don't create cross-class copies.

This doesn't change the behavior of SelectBitcast for X86.

Fix va_arg for doubles. With this patch VAARG nodes always contain the
correct alignment information, which simplifies ExpandRes_VAARG a bit.

The patch introduces a new alignment information to TargetLoweringInfo. This is
needed since the two natural candidates cannot be used:

* The 's' in target data: If this is set to the minimal alignment of any
  argument, getCallFrameTypeAlignment would return 4 for doubles on ARM for
  example.
* The getTransientStackAlignment method. It is possible for an architecture to
  have argument less aligned than what we maintain the stack pointer.

Use COPY in FastISel everywhere it is safe and trivial.

The remaining copyRegToReg calls actually check the return value (shock!), so we
cannot trivially replace them with COPY instructions.
