  [OpenMP] Change debugging symbol to weak_odr linkage

The new device runtime uses an internal variable to set debugging. This
variable was originally privately linked because every module will have
a copy of it. This caused problems with merging the device bitcode
library because it would get renamed and there was not a way to refer to
an external, private symbol. This changes the symbol to weak_odr so it
can be defined multiply, but will not be renamed.

  [OpenMP] Implement __assert_fail in the new device runtime

This patch implements the `__assert_fail` function in the new device
runtime. This allows users and developers to use the standars assert
function inside of the device.

  [OpenMP] Add support for dynamic shared memory in new RTL

This patch adds support for using dynamic shared memory in the new
device runtime. The new function `__kmpc_get_dynamic_shared` will return a
pointer to the buffer of dynamic shared memory. Currently the amount of memory
allocated is set by an environment variable.

In the future this amount will be added to the amount used for the smart stack
which will be configured in a similar way.
