Message:

Update to llvm-11.0.0 and rustc-1.47.0.

Patch firefox and thunderbird for this version of rust.
Remeasure all packages which use rust -
I think I used an out of date mozconfig when I updated thunderbird.
In general, builds are slower and slightly larger, but installs are marginally smaller.
