[Patch] omp-grid.c – add cast to silence different enumeration types warning

[Tobias Burnus]

Hi,

that's based on https://users.suse.com/~mliska/clang-warnings.txt
which has for omp-grid.c:

/home/marxin/BIG/buildbot/buildworker/marxinbox-gcc-clang/build/gcc/omp-grid.c:1070:7:
 warning: comparison of two values with different enumeration types in switch 
statement ('enum tree_code' and 'omp_clause_code') [-Wenum-compare-switch]
/home/marxin/BIG/buildbot/buildworker/marxinbox-gcc-clang/build/gcc/omp-grid.c:1081:7:
 warning: comparison of two values with different enumeration types in switch 
statement ('enum tree_code' and 'omp_clause_code') [-Wenum-compare-switch]
/home/marxin/BIG/buildbot/buildworker/marxinbox-gcc-clang/build/gcc/omp-grid.c:1082:7:
 warning: comparison of two values with different enumeration types in switch 
statement ('enum tree_code' and 'omp_clause_code') [-Wenum-compare-switch]
/home/marxin/BIG/buildbot/buildworker/marxinbox-gcc-clang/build/gcc/omp-grid.c:1083:7:

statement ('enum tree_code' and 'omp_clause_code') [-Wenum-compare-switch]

Those are all for the same switch statement;

gomp_for contains 'tree clauses' and this clauses's '->code' is used
to handle store 'enum omp_clauses_code' values in in gimple.{h,c}.

I think adding this cast (and only this one) makes sense and it
also silences a (clang) compiler warning.

OK?

Tobias
