This patch changes link_shaders() so that it sets prog->LinkStatus to
true when it starts, and then relies on linker_error() to set it to
false if a link failure occurs.
Previously, link_shaders() would set prog->LinkStatus to true halfway
through its execution; as a result, linker functions that executed
during the first half of link_shaders() would have to do their own
success/failure tracking; if they didn't, then calling linker_error()
would add an error message to the log, but not cause the link to fail.
Since it wasn't always obvious from looking at a linker function
whether it was called before or after link_shaders() set
prog->LinkStatus to true, this carried a high risk of bugs.

Previously we failed to link (which is correct), but we did not output
an error message, which could have been confusing for users.

Verify that interface blocks match when combining compilation
units at the same stage. (For example, when merging all vertex
shaders.)

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.
