In addition, crossjumping calls to abort does more than just save space; 
it also saves time, because space *is* time on modern processors, where 
every bit of icache counts.

I don't see any reason for GCC to treat "abort" specially.  It should at 
least treat all "noreturn" functions equivalently.  But, beyond that, 
I'm a user who would rather than crossjumping be run on calls to 
"abort".  I use "abort" only when I've already issued a useful 
diagnostic, and want to dump core.  Otherwise, I use "assert", or an 
exception.  So, I would not support this change.
