  -----------
  Correctly propagate pc ranges for blocks and local variables (#1226)

- fix valid pc address ranges for local variables that are declared in a
  sub-block (brace, try and catch blocks) of their function
- fix Context class's constructors so they correctly initialize and copy
  all member (use in-class initialize and default constructors)
