  1. Move C++ vtables into IRAM, out of HEAP 

    GCC places vtables in .rodata, with a mangled name of "_ZTV*."  Because
these are simply address jump tables, there is no need to place them in
RAM.  Instead, have the linker place them in the .text (aka IRAM) section.
This will free up a variable amount of heap space, depending on the number
of classes with virtual functions used in any particular project.
