Harmonising certain command line switches between GDC and LDC

[Cecil Ward]

Would it be possible for the maintainers of GDC and LDC to both 
support certain switches in use by the other compiler in order to 
reduce the frustration of this one grumpy user?

I keep switching back and forth between -frelease and -release,
and -march and -mcpu (is that even correct)?

I’m not sure what I should be doing to get LDC correctly matched 
with -mtune and -march.

I have of course ended up having to write batch files to abstract 
these annoyances away. When I’m examining generated code for my 
own correctness in godbolt.org Matt Godbolt’s Compiler Explorer, 
that’s when it drives me bonkers having to correct the switches 
when I switch between compilers.

It’s just a small thing, I know, but it would be nice to 
harmonise, and not too much work.
