go out of its way to understand code which hasn't been
InstCombined, analysis utility routines like this can
find themselves being called in the middle of transform

Fix Neon intrinsic immediate range checking for some double-register operands.
Some quad-register intrinsics with lane operands only take a double-register
operand for the vector containing the lane. The valid range of lane numbers
is then half as big as you would expect from the quad-register type.
Note: This currently has no effect because those intrinsics are now handled
entirely in the header file using __builtin_shufflevector, which does its own
range checking, but I want to use this for generating tests.
