Mikhail Glushenkov e4ac23a0ff Validate the generated C++ code in llvmc tests.
Checks that the code generated by 'tblgen --emit-llvmc' can be actually
compiled. Also fixes two bugs found in this way:

- forward_transformed_value didn't work with non-list arguments
- cl::ZeroOrOne is now called cl::Optional
