Keir Fraser f2cca23a87 hvmloader: Switch to absolute addressing for calling hypercall stubs. 
This is clearer and less fragile than trying to make relative calls
work. In particular, the old approach failed if _start was not
== HVMLOADER_PHYSICAL_ADDRESS. This was the case for some modern
toolchains which reorder functions.

Keir Fraser 65d3e7529c hvmloader: Fix _start-relative calculation of hypercall page address. 
We got away with it because _start-HYPERCALL_PHYSICAL_ADDRESS happens
to equal HYPERCALL_PHYSICAL_ADDRESS.
