runtime/race: switch to explicit race context instead of goroutine id's
Removes limit on maximum number of goroutines ever existed.
code.google.com/p/goexecutor tests now pass successfully.
Also slightly improves performance.
Before: $ time ./flate.test -test.short
real	0m9.314s
After:  $ time ./flate.test -test.short
real	0m8.958s
Fixes issue 4286.
The runtime is built from llvm rev 174312.
