CTFE-PGO ... Because I was bored

[Stefan Koch via Digitalmars-d]

Hi Guys,

Implementing and TESTING function-call support is boring so ...

I have just written a little piece of code that counts which 
switch-cases are executed most frequently versus how often their 
conditions are evaluated.

This can essentially be the basis for pgo based on the 
ctfe-function path.
Since functions are supposed to be the same at ctfe and at 
runtime, you basically get profiling information for free while 
compiling.

Cheers,
Stefan
