Huihui Zhang f4f2706572 [ConstantFold][SVE] Fix constant folding for scalable vector compare instruction.
Summary:
Do not iterate on scalable vector. Also do not return constant scalable vector
from ConstantInt::get().
Fix result type by using getElementCount() instead of getNumElements().

Huihui Zhang 5350a48931 [ConstantFold][SVE] Fix constant fold for FoldReinterpretLoadFromConstPtr.
Summary:
Bail out early for scalable vectors. As global variables are not expected
to be scalable.

Use explicit call of getFixedSize() to assert on places where scalable size
doesn't make sense.

Huihui Zhang 5389ca7a1f [ConstantFold][NFC] Move scalable vector unit tests under vscale.ll 2020-02-05 16:03:51 -08:00
Huihui Zhang b0d25fff9b [ConstantFold][SVE][NFC] Add test for select instruction in scalable vector.
Side notes from D73669, no need to guard the iteration on vectors, as
it is explicitly looking for a ConstantVector/ConstantDataVector, which
is not expected to be scalable at the moment. So, add the test only.

Huihui Zhang 34e6552dcb [ConstantFold][SVE] Fix constant folding for scalable vector unary operations.
Summary:
Similar to issue D71445. Scalable vector should not be evaluated element by element.
Add support to handle scalable vector UndefValue.
