Jason Molenda de905773ae Add quick bit of doc about SBFrame::GetCFA().

Greg Clayton 424a5dbc73 Added a new API to SBFrame:
lldb::addr_t SBFrame::GetCFA();

This gets the CFA (call frame address) of the frame so it allows us to take an address that is on the stack and figure out which thread it comes from.

Also modified the heap.py module to be able to find out which variable in a frame's stack frame contains an address. This way when ptr_refs finds a match on the stack, it get then report which variable contains the pointer.

Greg Clayton 4e1042e1bf Allow expresions to have unique expression prefixes:
expr_options = lldb.SBExpressionOptions()
expr_options.SetPrefix('''
struct Foo {
   int a;
   int b;
   int c;
}
'''
expr_result = frame.EvaluateExpression ("Foo foo = { 1, 2, 3}; foo", expr_options)

This fixed a current issue with ptr_refs, cstr_refs and malloc_info so that they can work. If expressions define their own types and then return expression results that use those types, those types get copied into the target's AST context so they persist and the expression results can be still printed and used in future expressions. Code was added to the expression parser to copy the context in which types are defined if they are used as the expression results. So in the case of types defined by expressions, they get defined in a lldb_expr function and that function and _all_ of its statements get copied. Many types of statements are not supported in this copy (array subscript, lambdas, etc) so this causes expressions to fail as they can't copy the result types. To work around this issue I have added code that allows expressions to specify an expression specific prefix. Then when you evaluate the expression you can pass the "expr_options" and have types that can be correctly copied out into the target. I added this as a way to work around an issue, but I also think it is nice to be allowed to specify an expression prefix that can be reused by many expressions, so this feature is very useful.

Bruce Mitchener 17d2730ee0 Start to share SWIG interface files between languages.
Summary:
Move scripts/Python/interface to scripts/interface so that we
can start making iterative improvements towards sharing the
interface files between multiple languages (each of which would
have their own directory as now).

Test Plan: Build and see.
