Add initial integrated assembler w/ some Xmm ops.
Add a flag to use the integrated assembler.
Handle simple XMM binary op instructions as an initial example of how
instructions might be handled. This tests fixups in a very limited sense --
Track buffer locations of fixups for floating point immediates.
Patchset one shows the original dart assembler code (revision 39313), so that
it can be diffed.
