glslang: Add API override of version and profile for testing purposes.  From Lei Zhang <antiagainst@google.com>.

Add defaultProfile and forceDefaultVersionAndProfile into shader
compilation interface.

forceDefaultVersionAndProfile allows us to force parsing the input
shaders using defaultVersion and defaultProfile, regardless of
the #version directive in input shaders.

These two parameters enables us to programmatically invoke glslang
but specify version and profile from somewhere else like command
line.

The problem is that putting the while loop at the end of a pipeline was hiding any errors being generated by those tests.  The patch changes the script to use a case statement inside the while loop instead of "grep" on the outside.

glslang AEP: Geometry shader features nominally working.  (Full semantic check and turn on pending.)  Also picked up partial tessellation shader interface, shader_io_blocks, and mirrored OES set of extensions functionality.

glslang -> SPV: swap arguments as needed for OpVectorTimesScalar and OpMatrixTimesScalar, and check for correct types for those as well as OpMatrixTimesVector, OpVectorTimesMatrix, and OpMatrixTimesMatrix.

glslang AEP: The extension scheme, extension-enabled stage-existence testing, and compute-shader interface.  Still needs in/out blocks, unsized arrays, etc. before real testing can be done.

glslang front-end: Support relaxed error checking for bug 13724 "...initializer must be a constant expression..." because that change breaks existing shipping applications.  (Normal validation for portability testing still gives an error.)
