* legoscia/dialyzer/native_erlang_mode/OTP-15880/PR-2283:
  Allow native compilation when calling Dialyzer from Erlang

Invoking Dialyzer through the function dialyzer:run/1 instead of from
the command line activates "Erlang mode", meaning that warnings are
returned instead of printed, and that HiPE compilation of modules does
not take place.  With this change, HiPE compilation can optionally be
enabled in this situation by passing the option {native, true}.
Caching of natively compiled modules is enabled by default, but can be
turned off using the option {native_cache, false}.

By default Dialyzer tries to improve the readability of warnings.
Newlines are inserted before and inside types, signatures, and Erlang
code. Sometimes the newlines look misplaced. The raw format
(option --raw) is not affected.

Use the new --no_indentation option get the old behavior (no inserted
line breaks).

A note on the implementation. The types &c present in the warning
tuples are parsed, and then formatted using erl_pp, the Erlang Pretty
Printer. The alternative, to create message tuples with formatted
types, turned out to more complicated, and has no real benefits.

Also notice that the fixes for binaries (commit 9db8a098) and union
elements (commit a1e51d12) are required. As a consequence, messages
created before these commits using the --raw option cannot always be
indented.

This reverts commit 425889ba69b69a9b6fb14bfbef121d51b78e853a.
