David Majnemer 73a92d5136 X86: Don't crash if we can't decode the pshufb mask
Constant pool entries are uniqued by their contents regardless of their
type.  This means that a pshufb can have a shuffle mask which isn't a
simple array of bytes.

The code path which attempts to decode the mask didn't check for
failure, causing PR22559.
