Björn Lindqvist	70e9834f2f	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.	2016-04-22 19:21:15 +02:00
