runtime/race: update race runtime
This updates the runtime to HEAD to keep it aligned and fixes some bugs.
http://llvm.org/viewvc/llvm-project?view=revision&revision=285454
fixes the crash on darwin related to unaligned data section (#17065).
http://llvm.org/viewvc/llvm-project?view=revision&revision=285451
enables core dumps by default (#16527).
http://llvm.org/viewvc/llvm-project?view=revision&revision=285455
adds a hook to obtain number of races reported so far (#15972).
Can now be obtained with:
//go:nosplit
func RaceReportCount() int {
var n uint64
racecall(&__tsan_report_count, uintptr(unsafe.Pointer(&n)), 0, 0, 0)
return int(n)
}
Fixes #16527.
Fixes #17065.
Update #15972.
