Andrew Kelley b581da41f8 remove compiler directives
* add `setFnTest`, `setFnVisible`, `setFnStaticEval`,
   `setFnNoInline` builtin functions to replace previous
   directive functionality
 * add `coldcc` and `nakedcc` as keywords which can be used as part
   of a function prototype.
 * `setDebugSafety` builtin can be used to set debug safety features
   at a per block scope level.
 * closes #169
