c1096b7f1d glsl: fix lower jumps for returns when loop is inside an if
Previously we would just escape the loop and move everything
following the loop inside the if to the else branch of a new if
with a return flag conditional. However everything outside the
if the loop was nested in would still get executed.

Adding a new return to the then branch of the new if fixes this
and we just let a follow pass clean it up if needed.

Fixes:

d1f6f65697 glsl: Separate overlapping sentinel nodes in exec_list.
I do appreciate the cleverness, but unfortunately it prevents a lot more
cleverness in the form of additional compiler optimizations brought on
by -fstrict-aliasing.

No difference in OglBatch7 (n=20).
