Subject: CUDA layout corner cases/testing (#1881)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Add support for sizeOf/alignOf/offsetOf to stdlib.
Add $G intrinsic expansion that works of the generic parameters not the param type

* Test cuda layout.

* Fix CUDA layout issues.
Fix reflection to handle other built in types.
Fix __offsetOf

* Tests of reflection and layout as reported directly from CUDA.

* Comment about use of aligned size as size.

* Fix warning from VS.

* Check alignment is pow2.

* Small improvements to alignment calcs.

* Tab to spaces.

* Fix alignment pointer sizes on 32 bit OS for CUDA.

* Fix CUDA reflection on 32 bit.
