Fix bug when processing '?' operator: invalidate the old "Uninitialized" value of the block-level expression for ?.

Use custom diagnostics for static analysis checkers.  Added warnings
for dereferencing uninitialized values and divide-by-zeroes.

in the parser:

a bunch of bogus assumptions (and likely bugs), reduces the complexity of
the implementation, and facilitates more optimizations.

wrapping an EnumConstantDecl evaluates to an integer type that has a different
