When constructing vectors from elements, use poison instead of
undef as the base value. These literals always initialize all
elements (padding the remainder with zero), so that the choice
of base value does not affect semantics.
With this patch an undefined mask in a shufflevector will be printed as poison.
This change is done to support the new shufflevector semantics
for undefined mask elements.

This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.
The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.

The included test case triggered a sign assertion on the result in
`Success()`. This was caused by the APSInt created for a bitcast
having its signedness bit inverted. The second APSInt constructor
argument is `isUnsigned`, so invert the result of
`isSignedIntegerType`.
Relanding this patch after reverting. The test case had to be updated
to be insensitive to 32/64-bit extractelement indices.

Change "negative" into "invalid" and put "invalid" at the beginning of
the file name, following the bulk of the invalid tests in the
SemaOpenCL directory.
Use the "invalid-" prefix only for tests that contain only invalid
constructs.
Drop the "valid" suffix for CodeGen tests, as inputs in this directory
are supposed to be valid anyway.
