Sean Callanan 7ea3501bd8 Added support for calling functions from expressions.
Right now we mock up the function as a variadic
function when generating the IR for the call; we need
to eventually make the function be the right type if
the type is available.

Sean Callanan 4edba2d130 Added support for locating a function that is
referenced in the IR.  We don't yet support updating
the call to that function.

Sean Callanan 8ade104a0a Changed SymbolContext so when you search for functions
it returns a list of functions as a SymbolContextList.

Rewrote the clients of SymbolContext to use this
SymbolContextList.

Rewrote some of the providers of the data to SymbolContext
to make them respect preferences as to whether the list
should be cleared first; propagated that change out.

ClangExpressionDeclMap and ClangASTSource use this new
function list to properly generate function definitions -
even for functions that don't have a prototype in the
debug information.

Sean Callanan ddb46efcca Updated the IR converter for the target to eliminate
spurious guard variables on expression statics.

Updated the AST result synthesizer to eliminate the
unneeded result pointer.

Very rudimentary expressions now evaluate correctly
in the target using the new JIT-based mechanism.

Sean Callanan 289e07b9d0 Added logging:
- When we JIT an expression, we print the disassembly
  of the generated code
- When we put the structure into the target, we print
  the individual entries in the structure byte for
  byte.

Sean Callanan ebf7707e53 Modified TaggedASTType to inherit from ClangASTType
and moved it to its own header file for cleanliness.

Added more logging to ClangFunction so that we can
diagnose crashes in the executing expression.

Added code to extract the result of the expression
from the struct that is passed to the JIT-compiled
code.

Greg Clayton e1a916a74d Change over to using the definitions for mach-o types and defines to the
defines that are in "llvm/Support/MachO.h". This should allow ObjectFileMachO
and ObjectContainerUniversalMachO to be able to be cross compiled in Linux.

Also did some cleanup on the ASTType by renaming it to ClangASTType and
renaming the header file. Moved a lot of "AST * + opaque clang type *"
functionality from lldb_private::Type over into ClangASTType.

Sean Callanan 1d18066411 Added functionality to dematerialize values that were
used by the JIT compiled expression, including the
result of the expression.

Also added a new class, ASTType, which encapsulates an
opaque Clang type and its associated AST context.

Refactored ClangExpressionDeclMap to use ASTTypes,
significantly reducing the possibility of mixups of
types from different AST contexts.

Sean Callanan 6b4067c14e Added the necessary code to copy variables used by
an expression into the struct prepared for the JIT
compiled code to use.

Sean Callanan ea22d4288a Wrote the code that looks at a context to see
if the variables in that context allow a particular
JIT compiled expression to run in that context.

Sean Callanan 549c9f7f9a "expr -i" now performs the required transforms to
prepare the IR for JIT compilation.  We still need
to do the JIT compilation and move the arguments
in/out of target memory.

Sean Callanan f06ba8d89c Updated the expression parser to use proper logging when
looking for external variables.  Also cleaned up the log
messages coming from the DWARF interpreter.
