0a40cd2661 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 #4286.
The runtime is built from llvm rev 174312.

ccc61eadd5 runtime: implement range access functions in race detector.
Range access functions are already available in TSan library
but were not yet used.

Time for go test -race -short:

Before:
compress/flate 24.244s
exp/norm       >200s
go/printer     78.268s

After:
compress/flate 17.760s
exp/norm        5.537s
go/printer      5.738s

Fixes #4250.

0ce96f9ef4 runtime: better stack traces in race reports
When a race happens inside of runtime (chan, slice, etc),
currently reports contain only user file:line.
If the line contains a complex expression,
it's difficult to figure out where the race exactly.
This change adds one more top frame with exact
runtime function (e.g. runtime.chansend, runtime.mapaccess).

1a19f01a68 runtime/race: lazily allocate shadow memory
Currently race detector runtime maps shadow memory eagerly at process startup.
It works poorly on Windows, because Windows requires reservation in swap file
(especially problematic if several Go program runs at the same, each consuming GBs
of memory).
With this change race detector maps shadow memory lazily, so Go runtime must notify
about all new heap memory.
It will help with Windows port, but also eliminates scary 16TB virtual mememory
consumption in top output (which sometimes confuses some monitoring scripts).
