[ACTIVITY] report week ending 31 May

(Short week, three days.)

Progress: * VIRT-65 [QEMU upstream maintainership] + continuing with the conversion of the VFP decoder to 'decodetree'. With some useful advice from RTH I have now got a big chunk of it done, and it looks like this will provide: - better places to put "UNDEF if CPU doesn't have double support" checks - checks of "VFP enabled?" only after all UNDEF checks have happened - cleanup of a lot of code that uses some TCG globals cpu_F0 and cpu_F1, which is weird ancient style and overdue for a cleanup - a VFP decoder which isn't a single thousand-line function with multiple nested switch statements
