Bump bootstrap compiler to something more recent

[Geod24]

I was trying to bisect a regression introduced between v2.097 and v2.098.
Digger downloaded v2.079 and tried to compiler v2.098 with this, which segfaults the compiler.
I easily found the setting in the INI file to change the host compiler, but as time passes, it's more likely that people will hit this more.

[CyberShadow]

How can I reproduce this segfault?

[Geod24]

For clarity: dmd host (v2.079) SEGV, not digger.

$ mkdir -p test && cd test
$ cat >bisect.ini<<EOF           
bad  = v2.098.1
good = v2.097.1
tester = dmd --version
EOF

I can't reproduce it :(

It also doesn't happen on the server which builds dlang.org.

Any idea what might cause the segfault on this machine?
