a single register number. This fully implements promotion for inline asms,
expand is close but not quite right yet.

- Added option -relocation-model to set relocation model. Valid values include static, pic,
...
dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.
- Removed options -enable-pic and -ppc-static.
