Significant improvement: GEP used by a load or store no longer generates
...
a separate ADD; instead just use the indexed load/store instruction!
Also, a bug fix: folding a GEP with a leading non-zero index with
its predecessor was incorrect: now it only happens if the predecessor
is pointing to an indexable type (aka SequentialType).

Allow emission of names that start with an underscore. This is needed to

interface with code that uses symbols in the ansi-c protected namespace. In
most cases this comes from system header files, such as stdio.h. In particular,
without this change, a reference to the __iob symbol is mangled into ll_iob,
which is not resolved by libc.

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.

code generation, and (b) selection does not have to deal with them.
