For crashes with a VFS (ie, with modules), the -isysroot flag is often
necessary to reproduce the crash. This is especially true if some
modules need to be rebuilt, since without the sysroot they'll try to
read headers that are outside of the VFS.
I find it likely that we should keep some of the other -i flags in
this case as well, but I haven't seen that come up in practice yet so
it seems better to be conservative.

When a crash report script doesn't work for a reproduction on your
machine for one reason or another, it can be really tricky to figure
out why not. The compiler version that crashed and the original
command line before stripping flags are very helpful when this comes
up.

This fixes crash report generation when filenames have spaces. It also
removes an awkward workaround that quoted *some* arguments when
generating crash reports.

When we create a crashdump involving modules, we build a VFS to
reproduce the problem with. This updates the reproduction script to
use that VFS.
