Parse all the C statements

[ForNeVeR]

We should fully implement the following section of the C standard:

• [ ] 6.8 Statements and blocks:
  • [ ] 6.8.1 Labeled statements
  • [x] 6.8.2 Compound statement
  • [x] 6.8.3 Expression and null statements
  • [ ] 6.8.4 Selection statements
  • [x] 6.8.5 Iteration statements
  • [x] 6.8.6 Jump statements

Look for the number 210 in the code to find clues to resolve this issue.
