* cfgexpand.c (get_decl_align_unit): Use LOCAL_DECL_ALIGNMENT
macro.
* defaults.h (LOCAL_DECL_ALIGNMENT): Define if not yet defined.
* config/i386/i386.h (LOCAL_DECL_ALIGNMENT): Define.
* config/i386/i386.c (ix86_local_alignment): For
-m32 -mpreferred-stack-boundary=2 use 32-bit alignment for
long long variables on the stack to avoid dynamic realignment.
Allow the first argument to be a decl rather than type.
* doc/tm.texi (LOCAL_DECL_ALIGNMENT): Document.
* gcc.target/i386/stackalign/longlong-1.c: New test.
* gcc.target/i386/stackalign/longlong-2.c: New test.
