Alberto Donizetti 375092bdcb cmd/compile: fix bogus "fallthrough statement out of place" ... When processing a fallthrough, the casebody function in swt.go checks that the last statement has indeed Op == OXFALL (not-processed fallthrough) before setting it to OFALL (processed fallthrough). Unfortunately, sometimes the fallthrough statement won't be in the last node. For example, in case 0: return func() int {return 1}() fallthrough the compiler generates autotmp_0 = (func literal)(); return autotmp_0; fallthrough; <node VARKILL> with an OVARKILL node in the last position. casebody will find that last.Op != OXFALL, won't mark the fallthrough as processed, and the fallthrough line will cause a "fallthrough statement out of place" error. To fix this, we change casebody so that it searches for the fallthrough statement backwards in the statements list, without assuming that it'll be in the last position.
