interface with code that uses symbols in the ansi-c protected namespace. In

Several major fixes, particularly in emitting constant aggregates:
...
(1) Padding bytes between structure fields (for alignment) were never
being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
were never handled.
(3) Support new model for external/uninitialized/initialized globals.
Uninitialized globals are no longer emitted since they are external.
Initialized globals may go either in .bss or in .data.

Major fix: extract ConstantExpr nodes and decompose them into symbolic

instructions so that (a) constant folding is done automatically before
code generation, and (b) selection does not have to deal with them.
