Improve performance of file I/O.
...
The fread / fwrite calls were happening for each timer. However, that could be
pretty expensive for a large number of timers. Instead, read and write the
timers in one call.
This gives ~10% speedup in compilation time.

[ASan] Make init-order checker allow access to already initialized globals.
...
This change adds ASan runtime option "strict-init-order" (off by default)
that makes init-order checker bark if global initializer accesses any global from different
translation unit (even if the latter is already initialized). strict init-order checking
doesn't play well with, e.g. LLVM registration machineries, and causes issue
https://code.google.com/p/address-sanitizer/issues/detail?id=178 .
