Subject: [PATCH] [mlir][spirv] Fix tablegen generator script's stripping of
prefixes
This script looks for existing definitions with the SPIRV_ prefix, so
that it can preserve them when updating the file. When the commit
2d628330482e49d36744cb8f3fb5047cfeae6c56 changed the prefix from SPV_,
the number of characters to strip from matched names was not updated,
which broke this feature. This commit fixes remaining cases that weren't
fixed by 339c87a8a086347bd8b5aae8b5bc43fc1c155cc1.
The relationship of this script to the files it is meant to maintain is
still bitrotten in other ways.
