libgo: Always initialize semaphores.
2011-04-03 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE>
PR go/48222
* runtime/malloc.goc (runtime_mallocinit): Call
runtime_Mprof_Init, runtime_initfintab.
* runtime/cpuprof.c (runtime_cpuprofinit): New function.
* runtime/runtime.h (runtime_cpuprofinit): Declare it.
* runtime/go-main.c (main): Use it.
