middle-end/101824 - properly handle volatiles in nested fn lowering
When we build the COMPONENT_REF of a formerly volatile local off
the FRAME decl we have to make sure to mark the COMPONENT_REF
as TREE_THIS_VOLATILE. While the GIMPLE operand scanner looks
at the FIELD_DECL this is not how volatile GENERIC refs work.

PR middle-end/101824
* tree-nested.c (get_frame_field): Mark the COMPONENT_REF as
volatile in case the variable was.
* gcc.dg/tree-ssa/pr101824.c: New testcase.
