When INT64_MIN is the value of a Sint64 we have to first cast it to
an Uint64 before negating it. Otherwise we get an integer overflow
which is undefined behaviour and in gcc 4.9 this results in -0 instead
of -9223372036854775808 in gcc 4.8.

While current run-queue lock is unlocked in the call to
erts_check_emigration_need() from erts_port_task_schedule() the
port can be migrated to another run-queue by another thread.
The code in erts_port_task_schedule() needs to check if this
has occurred when returning from erts_check_emigration_need(), and
if so respect the migration decision. When this was not done,
the thread calling erts_port_task_schedule() held the wrong
run-queue lock which caused invalid updates of the port task queue.
This bug was automatically fixed by the rewrites in the branch
rickard/r16b/port-optimizations-fixes/OTP-10336 (commit
56cef897ca3ad2377e34a6ea5800a54a28cbeb6e) introduced in erts-5.10
and do not effect erts versions after that.

The counter for the amount of outstanding data in the port queue
became inconsistent when aborting nosuspend-signals in
erts_port_task_schedule(). This since the counter was subtracted
by the data size of the signal although the data size had never
been added to it. This inconsistency caused the port queue to
remain in a busy state forever.

Similar to debugging with Valgrind, it's very useful to enable
-fsanitize= switches to catch bugs at runtime.

This fixes a bug introduced in f11aabdc9fec593c31e6c4f3fa25c1707e9c35df where
filelib:eval_read_file_info/2 was made to use file:read_link_info/1 to never
follow symlinks. This fixed wildcard/1 but broke every other function using
eval_read_file_info/2.

Specify in the documentation that erlang:statistics(runtime) returns milliseconds.

As there is no overflow for signed integers, -SINT_MIN is undefined behaviour
and the cast to unsigned needs to happen before negation. SINT_MIN denotes the
minimum value that can be stored in the Sint type.
beam/big.c:1512:6: runtime error: negation of -9223372036854775808 cannot be represented in type 'Sint' (aka 'long'); cast to an unsigned type to negate this value to itself
