  Log Message:
  -----------
  [OpenMP] Use function tracing RAII for runtime functions.

This patch adds support for using function tracing features to track the
executino of runtime functions in the device runtime library. This is
enabled by first compiling the new runtime with
`-fopenmp-target-debug=3` and running with
`LIBOMPTARGET_DEVICE_RTL_DEBUG=3`. The output only tracks team 0 and
thread 0 so there isn't much output when using a generic region.

  -----------
  [OpenMP] Check output of malloc in the device for debug

A common problem is the device running out of global heap memory and
crashing due to a nullptr dereference when using the data sharing stack.
This explicitly checks that a nullptr was not returned by malloc when
debugging field 1 is enabled.
