runtime: add GODEBUG=gccheckmark=0/1
Previously, gccheckmark could only be enabled or disabled by calling
runtime.GCcheckmarkenable/GCcheckmarkdisable. This was a necessary
hack because GODEBUG was broken.
Now that GODEBUG works again, move control over gccheckmark to a
GODEBUG variable and remove these runtime functions. Currently,
gccheckmark is enabled by default (and will probably remain so for
much of the 1.5 development cycle).
