A bug fix needs immediately attention, but a new feature may need more
discussion to make it easier to be used correctly.  I'm still reluctant
about "adding a whole bunch of new relocation just 3 weeks before
Binutils-2.39 release date".

About "LO12/HI20/LO20/HI12" vs "0/12/32/52", please consider: if someone
has not read LoongArch manual, he'll have no idea about what is "HI20"
and likely [mis]interpret it as "x[63:44]" instead of "x[51:32]".  But
if he has read LoongArch manual, the manual already uses
"LU12I.W/LU32I.D/LU52I.D".  So a different notion for the parts of
immediate seems a completely unnecessary deviation.
