re: r0 is not a base register - the last shortlisted row withdrawn

Browse Source 
sub_825F2CF0 / sub_825F2F88 (r0, 30 names each, 97% disc names) are not
name-block readers at all: they are the compiler's VMX save/restore helper
pair. 145 instructions each, 72 differ, every difference stvx<->lvx over
v14..v127.

Root cause: in `addi rD, rA, N` the rA slot reads as literal zero when it
names r0, so `addi r11, r0, -N` is `li r11, -N` - vector spill offsets, not
displacements. The solver excluded r1 only; the bogus base landed inside the
stage-settings name block, dense enough to "resolve" 30 real field names.

name_block_bases.py now skips r0 as well. Rows 277 -> 261, functions 190 ->
176, non-64K bases 170 -> 154, data-table rows 53 -> 50; 154+107=261 and
277-16=261. Artefact diff -100/+3, every removed row line carries r0, control
sub_82341A20 r30 = 0x82088F94 217/226 untouched.

Nothing lost: all 30 names are a strict subset of sub_8230D1F8 r29 (129
names), the stage-settings loader already in the corpus. String-xref join
agrees - FinalPassBG, FogMinDistance, ScreenColorR, ExposureKey_BeginValue
each exist once with exactly one xref, from sub_8230D1F8.

Fourteen other artefacts byte-identical; name-block-bases.txt byte-identical
on a second run.
