Rémy Oudompheng 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.

README 

runtime/race package contains the data race detector runtime library.
It is based on ThreadSanitizer race detector, that is currently a part of
the LLVM project.

To update the .syso files you need to:
$ svn co http://llvm.org/svn/llvm-project/compiler-rt/trunk
$ cd compiler-rt/lib/tsan/go
$ ./buildgo.sh

Tested with gcc 4.6.1 and 4.7.0.  On Windows it's built with 64-bit MinGW.
