trace: improve usefulness of hypercall trace record
Trace hypercalls using a more useful trace record format.
The EIP field is removed (it was always somewhere in the hypercall
page) and include selected hypercall arguments (e.g., the number of
calls in a multicall, and the number of PTE updates in an mmu_update
etc.). 12 bits in the first extra word are used to indicate which
arguments are present in the record and what size they are (32 or
64-bit).
This is an incompatible record format so a new event ID is used so
tools can distinguish between the two formats.
