PR middle-end/65958
* gimplify.c (struct gimplify_ctx): Turn boolean fields into 1-bit
fields, add keep_stack and reorder them.
(gimplify_bind_expr): Save gimplify_ctxp->keep_stack on entry then
set it to false. Do not insert a stack save/restore pair if it has
been set to true by the gimplification of the statements.
Restore it to the saved value on exit if it is still false.
(gimplify_vla_decl): Do not set gimplify_ctxp->save_stack here.
(gimplify_call_expr) <BUILT_IN_ALLOCA[_WITH_ALIGN]>: New case. Set
either save_stack or keep_stack depending on CALL_ALLOCA_FOR_VAR_P.
* doc/extend.texi (Variable Length): Document new behavior.
* doc/generic.texi (Blocks): Document new handling of VLAs.
