This change makes `this` a reference instead of a pointer in HLSL. HLSL does not have the `->` operator, and accesses through `this` are with the `.` syntax. Tests were added and altered to make sure the AST accurately reflects the types. Reviewed By: aaron.ballman Differential Revision: https://reviews.llvm.org/D135721
