PR debug/54828
* gimple.h (is_gimple_sizepos): New inline function.
* gimplify.c (gimplify_one_sizepos): Use it. Remove useless
final assignment to expr variable.
* tree.c (RETURN_TRUE_IF_VAR): Return true also if
!TYPE_SIZES_GIMPLIFIED (type) and _t is going to be gimplified
into a local temporary.
* g++.dg/debug/pr54828.C: New test.
