Issue Description:

Hi!

When using generic numeric functions with more or less complicated expressions the compiler gives up.

See the example in the attached playground content.

Same happens when using Xcode 10 GM.
Added a new example.

It is very disappointing that the support of generic numeric functions is so poor. This makes Swift useless for scientific software at this time.

Unfortunately there is no improvement even with the new version. Are there no new findings?

Regards!
