that it no longer handles non-power-of-two vectors.
However it previously only handled them sometimes,

the index and vector type.  For example, for a vector
of length 6, it would succeed if and only if the
index was an even multiple of 6.  I consider this

- Make sure that we don't over-increment the iterator when going through the
  basic blocks.
- Minor code clean-up.

Added CONVERT_RNDSAT (conversion with rounding and saturation) SDNode to
support targets that support these conversions. Users should avoid using
this node as the current targets don't generating code for it.

Fix PR2667: add soft float support for sint_to_fp/uint_to_fp
where the argument is an apint, or smaller than the minimum
size for which there is a libcall (i32).

Small cleanups.  No functionality change intended!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58992 91177308-0d34-0410-b5e6-96231b3b80d8

When promoting the result of fp_to_uint/fp_to_sint,
inform the optimizers that the result must be zero/
sign extended from the smaller type.  For example,
if a fp to unsigned i16 is promoted to fp to i32,
then we are allowed to assume that the extra 16 bits
are zero (because the result of fp to i16 is undefined
if the result does not fit in an i16).  This is
quite aggressive, but should help the optimizers
produce better code.  This requires correcting a
test which thought that fp_to_uint is some kind
of truncation, which it is not: in the testcase
(which does fp to i1), either the fp value converts
to 0 or 1 or the result is undefined, which is
quite different to truncation.

Really fix testb optimization on big-endian.

Third time's a charm.

The previous patches didn't match correctly. Also, we need to make sure that
the conditional is the same before doing the transformation.

Added support for the following definition of shufflevector
