This introduces a small regression on the generated code
quality in the case we are just computing addresses, not
loading values.

Will work on it and on X86-64 support.

When compiling in Thumb mode, only the low (R0-R7) registers are available
for most instructions. Breaking the low registers into a new register class
handles this. Uses of R12, SP, etc, are handled explicitly where needed
with copies inserted to move results into low registers where the rest of
the code generator can deal with them.

Types can have references to eachother, so we can't just call destroy on them.

Map stack based frameindices for spills to zero based indices that can be accessed based on an external symbol defining the location of temporary data for a function. For example: we have spill slots addressed as foo.tmp + 0, foo.tmp + 1 etc.

To convert the StopPoint insn into an assembler directive by ISel, we need to have access to the line number field. So we convert that info as an operand by custom handling DBG_STOPPOINT in legalize.

Params are not being generated as static globals now. The caller passes them onto the callee's stack directly and the callee loads the argvals from its own stack. Clang generated frameindexes validatd by recalculating the stack as if all frameindexes represent 1-byte slots.

 - The code is silly, I'm just amusing myself. Rewrite to be efficient
   if you like. :)

Also, if you wish to debate the proper names of the triple components
I'm all ears.

calculations from target-oriented calculations.
