SVal::GetRValueSymbolVal do the checking if we can symbolicate a type instead of
having BasicStoreManager do it (which wasn't always doing the check
consistently). Having this check in SVal::GetRValueSymbolVal keeps the check in
one centralized place.

if our usual methods fail. This isn't necessary for running the tool,
but improves the accuracy of logging output.

Also, have GCC tools lookup gcc program path.

declarations for controlling groups of warnings. Currently this transforms:

  def UnusedMacrosDiags : Option<"unused-macros", [pp_macro_not_used]>;
  
into:

and the token after the # should be expanded if it is not a valid directive.
This allows us to transform things like:

#define FOO BAR
# FOO

into # BAR, even though FOO is not normally expanded for directives.
