runtime: merge mallocgc, gomallocgc
I assumed they were the same when I wrote
cgocallback.go earlier today. Merge them
to eliminate confusion.
I can't tell what gomallocgc did before with
a nil type but without FlagNoScan.
I created a call like that in cgocallback.go
this morning, translating from a C file.
It was supposed to do what the C version did,
namely treat the block conservatively.
Now it will.
