If the LoopConvert Transform detects an alias for the loop variable, it
attempts to use that name in the resulting range-based for loop while removing
the original DeclStmt for the variable. That removal produced bad code when the
declaration was in the condition of an if, switch, while, or for stmt. This
revision fixes the problem by simply replacing the declaration with a use of
the alias variable.

Summary:
Transform.* and Transforms.* moved to form a new library: libmigrateCore.
#includes updated to point to new header locations.
To support autoconf build, Cpp11Migrate.cpp moved to new subdirectory 'tool'
which also contains build files for creating final binary.
CMake and autoconf updated to build the new library and link it with
cpp11-migrate and with cpp11-migrate unit tests.
Dummy unit tests replaced with simple, but real, tests for Transform's public
interface.
TODO: Lib-ifying the transforms to further simplify build of cpp11-migrate.

For iterators where the dereference operator returns by value, LoopConvert
should use 'auto &&' in the range-based for loop expression.
If the dereference operator returns an rvalue reference, this is deemed too
strange and the for loop is not converted.
Moved test case from iterator_failing.cpp to iterator.cpp and added extra
tests.
Fixes PR15437.

Took existing code from loop-convert tool and made it into a cpp11-migrate
transform. Pattern now set for having transform code in subdirectories. Related
changes:
- Makefile and CMakeLists.txt updated to support source files in
subdirectories.
- At least one transform must be specified. syntax-only tests removed to
reflect this.
- TODO: port over loop-convert tests.
