since compile_fdesignator skips compile_form, the code walker wouldn't see e.g. the c-n-m in (funcall #'call-next-method ...).
From a few microbenchmarks this appears to improve some performance marginally; but I'd like to include it for other reasons: 1) This way (apply #'foo ...) shows up as a call to FOO in xref, and not as a call to APPLY. 2) The bytecode is a little nicer for BTB purposes since this matches how we treat APPLY in clasp-cleavir. It matches the philosophy of having M-V-C as _the_ variadic call mechanism.
This lets us move the APPLY compiler macro out of cclasp-specific-land.

Some minor performance improvements to how the VM handles multiple values. Mostly it lets the compiler macro expanding
applyintomultiple-value-callbe shared between bytecode and cclasp, which I think is nice.This is hardly a high priority and it changes the VM definition, so this'll be a draft for a while
