Andrea Di Biagio	3647a96a44	[InstSimplify] Add tests to show missed bitcast folding opportunities. InstSimplify doesn't always know how to fold a bitcast of a constant vector. In particular, the logic in InstSimplify doesn't know how to handle the case where the constant vector in input contains some undef elements, and the number of elements is smaller than the number of elements of the bitcast vector type. llvm-svn: 281332	2016-09-13 13:17:42 +00:00

[InstSimplify] Add tests to show missed bitcast folding opportunities.

InstSimplify doesn't always know how to fold a bitcast of a constant vector.
In particular, the logic in InstSimplify doesn't know how to handle the case
where the constant vector in input contains some undef elements, and the
number of elements is smaller than the number of elements of the bitcast
vector type.

Regenerate vector bitcast folding tests using update_test_checks.py.

Two tests have been merged together, regenerated and then moved to
a more appropriate directory. No functional change.
