The existing code handled the case where the new definition of the
same field was larger than the old one.
This commit adds a check to handle the reverse case: the new def
is smaller than the old one (= so writing using the merged macro
would affect the next fields).
The affected fields are:
* LGKM_CNT (in SQ_WAVE_IB_STS)
* DONUT_SPLIT (in VGT_TESS_DISTRIBUTION)
* HEAD_QUEUE (in GDS_GWS_RESOURCE)
DONUT_SPLIT is the only one used by radeonsi/radv.
Fixes: e6184b0892 ("amd/registers: scripts for processing register descriptions in JSON")

We will derive both the debugging tables and (the majority of) the
register headers from descriptions in JSON, instead of deriving the
debugging tables from an awkward parsing of the register headers.
Some of the scripts are useful for maintaining the register database
itself. The scripts are designed to output reasonably readable JSON
by default.
