Refactor GCC dump and GNAT expanded code creation (#3064)gh-1262

Instead of having a dedicated invocation of the compilers, inject needed options
in the main compilation command and do everything in one run. This should fix
GNAT race condition on ALI file, save some CPU time and make the latency a bit
better. This can work as long as everything can really be done in one run (eg.
no incompatible options, no clash on stdout/stderr).

Add optionsForBackend in base compiler class that is meant to be overloaded by
compilers for injecting options based on current backend options. Use it for
GCC dumps (BaseCompiler) and GNAT expanded code.

Fixes #3041
References #3029
