[clang] Fix signedness in vector bitcast evaluation
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.
