Subzero: Shorten and normalize strings in non-DUMP builds.
Jump table labels change from ".Lxxxxx_yy" to "$Jxxxxx_yy".
Pooled float labels change from ".L$float$xxxxyyyy" to "$Fxxxxyyyy".
Pooled double labels change from ".L$double$xxxxxxxxyyyyyyyy" to "$Dxxxxxxxxyyyyyyyy".
All these should in theory not conflict with C/C++ user symbols.
Float labels now likely fit into short strings and don't require extra memory allocation.
Double labels may exceed the limit - encoding in base64 instead of hex would fix that. Or, directly use the binary bytes as the string value.
