  -----------
  [NVPTX] Fix issues in ptxas integration to LIT tests

1) Fixed a typo in PTXAS_EXECUTABLE CMake variable (PXTAS -> PTXAS).

2) Version check was implemented incorrectly,
   now version (major, minor) is converted to int for comparison.

3) ptxas -arch argument was incorrect (or missing) in 3 tests.

  -----------
  [NVPTX] Fix constant expression initializers for global variables

Before this patch the code in printScalarConstant was unable to handle
nested constant expressions like (gep (addrspacecast ptr)) and crashed
with:

LLVM ERROR: Unsupported expression in static initializer:
  addrspacecast ([4 x i8] addrspace(1)* @ga to [4 x i8]*)

We can use lowerConstantForGV instead which is a customized version of
lowerConstant that supports generic() and nested expressions.
