PR c++/84964: Middle-end patch to expand_call for ICE after sorry.
This patch resolves PR c++/84969 which is an ICE in the middle-end after
emitting a "sorry, unimplemented" message, and is a regression from
earlier releases of GCC. This issue is that after encountering a
function call requiring an unreasonable amount of stack space, the
code continues and falls foul of an assert checking that stack pointer
has been correctly updated. The fix is to (locally) consider aborted
function calls as "no return", which skips this downstream sanity check.
