Add a new option to indicate we want the code generator to emit code quickly,not spending tons of time microoptimizing it.  This is useful for an -O0style of build.

Invert the TargetLowering flag that controls divide by consant expansion. · 4dd38312

Nate Begeman authored Oct 21, 2005

Add a new flag to TargetLowering indicating if the target has really cheap
  signed division by powers of two, make ppc use it.  This will probably go
  away in the future.

- Give ADJCALLSTACKDOWN/UP the correct operands. · e2967ac5
  Chris Lattner authored Aug 19, 2005
```
Give a whole bunch of other stuff variable operands, particularly FP.  The
FP stackifier is playing fast and loose with operands here, so we have to
mark them all as variable.  This will have to be fixed before we can dag->dag
the X86 backend.  The solution is for the pre-stackifier and post-stackifier
instructions to all be disjoint.
