erik.corry@gmail.com f5523ecc6a Split the virtual frame into heavy and light versions.
The heavy version is for x86 and x64.  The light version
is for ARM and MIPS.  Remove the elements_ array from the
virtual frame in the light version.  More simplifications
to come, followed by light register allocation.
