compiler: add alloc attributes to runtime.alloc

Browse Source 
This gives a small improvement now, and is needed to be able to use the
Heap2Stack transform that's available in the Attributor pass. This
Heap2Stack transform could replace our custom OptimizeAllocs pass.

Most of the changes are just IR that changed, the actual change is
relatively small.

To give an example of why this is useful, here is the code size before
this change:

    $ tinygo build -o test -size=short ./testdata/stdlib.go
       code    data     bss |   flash     ram
      95620    1812     968 |   97432    2780

    $ tinygo build -o test -size=short ./testdata/stdlib.go
       code    data     bss |   flash     ram
      95380    1812     968 |   97192    2780

That's a 0.25% reduction. Not a whole lot, but nice for such a small
patch.
