copy the source buffers provided rather than referencing them
directly, so that the caller can free those buffers immediately after
calling clang_createTranslationUnitFromSourceFile(). Otherwise, we
risk hitting those buffers later (when building source ranges, forming
diagnostics, etc.).

Use this information to find the returned value and bind it to CallExpr in
ProcessCallExit.
And there is no need to remove dead bindings in ProcessCallExit, because
a. it would clean up the return value bound to CallExpr
b. we still would do it in the next ProcessStmt(), where we would not misclean
   up the return value.

propagating error conditions out of the various annotate-me-a-snowflake

I have just signed myself up to fix fiddly parser errors for the next

equality comparisons, and conditional operators, produce a composite
pointer type with the appropriate additional "const" qualifiers if the
pointer types would otherwise be incompatible. This is a small
extension (also present in GCC and EDG in a slightly different form)
that permits code like:

  void** i; void const** j; 
  i == j; 

with the following extwarn:

t.cpp:5:5: warning: comparison of distinct pointer types ('void **' and
      'void const **') uses non-standard composite pointer type
      'void const *const *' [-pedantic]
  i == j;

This patch implements the CallEnter/CallExit idea of Ted.

Add two interfaces to GRSubEngine: ProcessCallEnter, ProcessCallExit.

The CallEnter program point uses caller's location context. The
CallExit program point uses callee's location context.

CallEnter is built by GRStmtNodeBuilder. CallExit is built by
GREndPathNodeBuilder.
