This is mostly defensive. If a convergent value ever ended up as a
source of a DDX or DDY, the eu_emit code will ignore the stride. This
will result in bad code being generated.
No shader-db or fossil-db changes on any Intel platform.
v2: DDX and DDY will always be float, but brw_imm_for_type only works
with integer types.

This prevents assertion failures in brw_eu_emit in a later commit in
this MR. Even though they have not been previously observed, these
assertion failures could happen even without that commit.
No shader-db or fossil-db changes on any Intel platform.
Fixes: 04e1783278 ("brw: Call brw_fs_opt_algebraic less often")
v2: Add SHUFFLE. Suggested by Ken. Fixed indentation.
v3: Update BROADCAST exec_size after rebasing on "brw/build: Use SIMD8
temporaries in emit_uniformize".
v4: Explain why munging the exec_size is correct.
