 cmm: Use LocalBlockLabel instead of AsmTempLabel to represent blocks

 blockLbl was originally changed in
 8b007abbeb3045900a11529d907a835080129176 to
 use mkTempAsmLabel to fix an inconsistency resulting in #14221. However,
 this
 breaks the C code generator, which doesn't support AsmTempLabels (#14454).

 Instead let's try going the other direction: use a new CLabel variety,
 LocalBlockLabel. Then we can teach the C code generator to deal with
 these as well.
