D.gnu - Support of -run and source code from stdin

Hi,
Dmd and ldc supports running source code from stdin:

```
echo 'void main(){}' | dmd -run -
```

It seems GDC does not support argument -run and I do not know 
wheter it supports reading source code from stdin?

Could this 2 featured be added to gdc?
This would solve the probe file issue mentioned here 
https://forum.dlang.org/post/uwxndbpxspwaofolksbr forum.dlang.org

Kind regards

I see no obvious use for having something like -run in the 
driver. Toolchain apps are more than capable of doing this 
themselves.

gdc -x d -

The -x tells gcc what language to parse, as the driver is capable 
of handling all languages gcc knows about, eg -xc++.

Looks like the description of the problem matches what this PR is 
fixing.

Thanks for the info.
The issue is not about the compiled artifacts but about the probe 
modules (source code).
In some cases, they are not deleted (There is a module destructor 
in dub which should take care of).

Kind regards
