Add thread pool class
Added a thread pool class loosely based on google3 code.
Modified the compiler to have a single thread pool instead of creating new threads in ForAll.
Moved barrier to be in top level directory as it is not GC specific code.
Performance Timings:
Reference:
boot.oat: 14.306596s
time mm oat-target:
real 2m33.748s
user 10m23.190s
sys 5m54.140s
Thread pool:
boot.oat: 13.111049s
time mm oat-target:
real 2m29.372s
user 10m3.130s
sys 5m46.290s
The speed increase is probably just noise.
