compiler.cfg.linear-scan.assignment: correct representation used when spilling
...
Previously the rep-of word was used. But as the vregs representation can
change, you need to instead use the representation it uas as the spill
point.

compiler.cfg.*: new system for emitting spill/reloads for gc calls ( #1471 )
...
GC calls were treated as sync points so all registers were spilled
around them. But if the gc call isn't triggered, it is unnecessary to
spill. This commit fixes that by handling ##call-gc specially and
putting ##spill and ##reloads in the same block as the gc call itself.
