[SystemZ] Bugfix in SystemZTargetLowering::combineINT_TO_FP()
Make sure to also handle extended value types to avoid crashing.
Resulting integers greater than 64 bits are not optimized (i128 is not a
legal type), and vectorizing seems to result in libcalls instead of just
scalarization.
Other extended vector types like <10 x float> are however now handled and
should result in vectorized conversions.

[SystemZ] Improve handling of ZERO_EXTEND_VECTOR_INREG.
Instead of doing multiple unpacks when zero extending vectors (e.g. v2i16 ->
v2i64), benchmarks have shown that it is better to do a VPERM (vector
permute) since that is only one sequential instruction on the critical path.
This patch achieves this by
1. Expand ZERO_EXTEND_VECTOR_INREG into a vector shuffle with a zero vector
instead of (multiple) unpacks.
2. Improve SystemZ::GeneralShuffle to perform a single unpack as the last
operation if Bytes matches it.

[SystemZ] Avoid scalarization of [SU]INT_TO_FP ISD-nodes.
The type legalizer will scalarize vector conversions from integer to floating
point if the source element size is less than that of the result.
This is avoided now by inserting a zero/sign-extension of the source vector
before type legalization.
