Subject: glsl: don't eliminate subroutine types.

X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f73ef824869dbb1f91c32ad563c95ca917f40c12;p=platform%2Fupstream%2Fmesa.git

glsl: don't eliminate subroutine types.

This stops dead code from removing subroutines types,
we need these for the queries to work properly.
