Revert "mesa: Remove pointless comparison of unsigned integer with a negative constant."
This reverts commit a05fdbcb719ac64e6be842372813f0f4ca2f4f93.
Removing the comparison is wrong. The comparison with -1 should be changed
to another value (probably PROGRAM_UNDEFINED) along with another
change in the shader assembler.
