Add support alignment of allocation instructions.

Add support for specifying alignment and size of setjmp jmpbufs.
No targets currently do anything with this information, nor is it presrved
in the bytecode representation. That's coming up next.

When a function takes a variable number of pointer arguments, with a zero
...
pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

Completely rewrite 'correct' eh support. This changes how setjmp insertion
...
is performed so it is only at most once per function that contains an invoke
instead of once per invoke in the function. This patch has the following perks:
1. It fixes PR631, which complains about slowness.
2. If fixes PR240, which complains about non-volatile vars being live across
setjmp/longjmps.
3. It improves (but does not fix) the jmpbuf alignment issue on itanium by not
forcing the jmpbufs to always be 8-bytes off the alignment of the structure.
4. It speeds up 253.perlbmk from 338s to 13.70s (a 25x improvement!), making us
now about 4% faster than GCC.
Further improvements are also possible.
