John Stiles f201af8b00 Allow more types of expressions to be directly inlined.
The following types of expression are hoisted directly into the
inlined code:

- Struct field access: `myStruct.myField`
- Swizzles: `myVector.xzy`
- Simple array indexes: `myArray[0]`

This significantly reduces the number of temporary variables generated
by the inliner.
