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.

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.

[TSan] Allocate fd table in user heap instead of using internal allocator. We need this to catch races on fds.

This was committed without tests and contains obvious bugs. That's not
acceptable. It broke address sanitizer for most programs using glob(3).

Add a regression test for the case where such behavior helps TSan:
  1. race is reported in the main module
  2. new shared library is loaded
  3. race is reported in the shared library
