There are two forms. Swizzle::Make supports components XYZW only;
Swizzle::MakeWith01 also supports the 01 components, and restructures
the zeros and ones into a constructor (as IRGenerator::convertSwizzle
has historically done). This means that once we are past the initial
IR generation stage, and we know that the 01 components have been
eliminated, we can avoid the extra 01-handling logic and just call
Swizzle::Make directly. This isn't a huge deal but it means that call
sites like the inliner can avoid some extra work that will never happen.

When SPIR-V generates function calls to an intrinsic, it assumes that
it can get a pointer to out-parameters referenced by the intrinsic.
This does not account for swizzled out-parameters; these are valid
lvalues, but do not work with getPointer().
The two intrinsics supported by SkSL which have an out-parameter are
frexp and modf, so these tests were fleshed out to trigger the error.
Neither of these are supported in ES2, though, so we cannot test them
via Runtime Effects.

This will allow us to load these inputs for unit testing in `dm`.
