This fixes erroneously reported CUDA compilation errors
in host-side code during device-side compilation.
I've also restricted OpenMP-specific checks to trigger only
if we're compiling with OpenMP enabled.

Summary:
Previously, when you did something not allowed in a host+device function
and then caused it to be codegen'ed, we would print out an error telling
you that you did something bad, but we wouldn't tell you how we decided
that the function needed to be codegen'ed.
This change causes us to print out a callstack when emitting deferred
errors. This is immensely helpful when debugging highly-templated code,
where it's often unclear how a function became known-emitted.
We only print the callstack once per function, after we print the all
deferred errors.
This patch also switches all of our hashtables to using canonical
FunctionDecls instead of regular FunctionDecls. This prevents a number
of bugs, some of which are caught by tests added here, in which we
assume that two FDs for the same function have the same pointer value.
