Improve taint analysis a little

on GitHub

Taint analysis

• $_REQUEST is now treated as a source, and taints now flow through trim and similar funcs
• @psalm-taint-specialize now works in static methods

Also @TysonAndre added a --debug-emitted-issues command line flag to help debug the route of a Psalm issue.

Bugfixes

• preg_replace_callback now supports arrays properly even when the closure is not well-documented (#3639)
