Make gimple_build main workers more flexible
The following makes the main gimple_build API take a gimple_stmt_iterator, whether to insert before or after and an iterator update argument to make it more convenient to use in certain situations (see the tree-vect-generic.cc hunks for an example). It also makes the case we insert into the IL somewhat distinct from inserting into a standalone sequence in that it simplifies built expressions the same way as inserting and calling fold_stmt (..., follow_all_ssa_edges) would. When inserting into a standalone sequence we restrict simplification to defs within the currently building sequence.
The patch only amends the tree_code gimple_build API, I will followup with converting the rest as well. The patch got larger than intended because the template forwarders now use gsi_last which introduces a dependency on gimple-iterator.h requiring mass #include re-org across the tree. There are two frontend specific files including gimple-fold.h just for some padding clearing stuff - I've removed the include and instead moved the declarations to fold-const.h (but not the implementations). Otherwise I'd have to include half of the middle-end headers in those files which I didn't much like.

Make gimple_build main workers more flexible
The following makes the main gimple_build API take a gimple_stmt_iterator, whether to insert before or after and an iterator update argument to make it more convenient to use in certain situations (see the tree-vect-generic.cc hunks for an example). It also makes the case we insert into the IL somewhat distinct from inserting into a standalone sequence in that it simplifies built expressions the same way as inserting and calling fold_stmt (..., follow_all_ssa_edges) would. When inserting into a standalone sequence we restrict simplification to defs within the currently building sequence.
The patch only amends the tree_code gimple_build API, I will followup with converting the rest as well. The patch got larger than intended because the template forwarders now use gsi_last which introduces a dependency on gimple-iterator.h requiring mass #include re-org across the tree. There are two frontend specific files including gimple-fold.h just for some padding clearing stuff - I've removed the include and instead moved the declarations to fold-const.h (but not the implementations). Otherwise I'd have to include half of the middle-end headers in those files which I didn't much like.
