object_allocator only allowed allocations to use the default constructor.
This patch generalises it to other constructors, in the same way as
rtl-ssa does for obstack allocations.
The first use case is likely to be Robin's backprop patch.
Tested on aarch64-linux-gnu, powerpc64le-linux-gnu & x86_64-linux-gnu.
OK to install?
