glsl linker: compare interface blocks during intrastage linking
Verify that interface blocks match when combining compilation
units at the same stage. (For example, when merging all vertex
shaders.)
Fixes piglit glsl-1.50 test:
* linker/interface-blocks-multiple-vs-member-count-mismatch.shader_test
v5 (Ken): Rename to link_interface_blocks.cpp and drop the separate .h
file for consistency with other linker code. Remove "ok" variable.
Fold cross_validate_interface_blocks into its caller.
