embedded may not have a heap, so make it hard to use, this makes it
impleemtation defined
 will provide all the replaceable functions or none of them
placement new still exists

presence of operator new is implementation defined, AND user does not
provide one, then it is ill-formed
IFNDR is not needed

there is usage experience in this
BS replaced global operator delete with something that does not exists; so
if someone accidentally uses the delete in question, the nprogram does not
build

STJ mentions providing no throw T placement new and needed to check for 0,
as user is surprised that may have a try catch in it

RF clarifies and codifies existing 2 or so minor variations
go to EWG first before may be going to LEWG
Forward P2013 as is with the minor editing quotes
SF/f/n/a/sa
9/10/0/0/0
approves to go to EWG
