This shouldn't compile

import typetraits

proc p(x: int8|int16) =
  echo x.type.name # int

p(1)

internal: implement --profiler:on support with MIR pass (nim-lang#1214
12f0aa4 
)

## Summary

Make routine instrumentation with `nimProfile` calls a MIR pass, moving
more logic out of the C code generator and working towards
`--profiler:on` support with all backends. `nimProfile` calls are also
no longer inserted into loops within `.asmNoStackFrame` routines.

## Details

* require a `ModuleGraph` instance for `mirpasses.applyPasses`, so that
  compilerprocs can be looked up
* add the `injectProfilerCalls` MIR pass. It injects `nimProfile` in
  the same way that `cgen` does
* remove injection of `nimProfile` calls from `cgen`
* don't instrument loops within `.asmNoStackFrame` procedures;
  injection of `nimProfile` at procedure entry was already skipped for
  these procedures
* temporarily remove the `optProfiler` option from symbols when in JIT
  mode, that code generated for compile-time execution is not
  instrumented
* add a test for the `--profiler:on` feature, to make sure it works and
  keeps working
