[tremor] good version of alloca()

[timmy brolin]

Yes, alloca() is far from common. It doesn't look like IAR systems have implemented it for example.

MS does provides a alloca function, but it is named differently. ___alloca() or something like that I think.

I think the deal is that alloca allocates from the stack instead of the
heap which is desirable in some situations. Given that there are quite a
few platforms where this isn't implementated, it might be nice to add a
level of abstraction with some #define magic that allows either alloca
to be selected or malloc if the former doesn't exist.
