49001d58 - [ubsan] Display correct runtime messages for negative _BitInt (#93612)

[ubsan] Display correct runtime messages for negative _BitInt (#93612) Without this patch compiler-rt ubsan library has a bug displaying incorrect values for variables of the _BitInt (previously called _ExtInt) type. This patch affects affects both: generation of metadata inside code generator and runtime part. The runtime part provided only for i386 and x86_64 runtimes. Other runtimes should be updated to take full benefit of this patch. The patch is constructed the way to be backward compatible and int and float type runtime diagnostics should be unaffected for not yet updated runtimes.
