Fix fct asm label: only valid for declaration

- Fix function assembly label mechanism introduced in commit
  9b09fc376e8c212a767c875e71ca003e3b9a0d2e to only accept alternative
  name for function declaration.
- merge the code with the one introduced in commit
  264a103610e3ee86b27b8cbb0e4ec81cd654d980.
- Don't memorize token for asm label but directly the asm label.
