* rounding modes for fp add, mul, sub now use .rn
* float -> int rounding correctly uses .rzi not .rni
* 32bit fdiv for sm13 uses div.rn (instead of div.approx)
* 32bit fdiv for sm10 now uses div (instead of div.approx)

Approx is not IEEE 754 compatible (and should be optionally set by a flag to the backend instead). The .rn rounding modifier is the PTX default anyway, but it's better to be explicit.

All these modifiers should be available by using __fmul_rz functions for example, but support will need to be added for this in the backend.

config.cache will be used by the person who specifies '-C' to configure.
config.cache's inconsistency should be responsible to him.

Re-configuration would spend so much on cygming without '-C', esp. cygwin.

The reserved R14-R15 are always saved in the prolog, and using CSRs
starting from R13 allows them to be saved in one instruction.

Also switch the return type to ArrayRef<unsigned> which works out nicely
for ARM's implementation of this function because of the clever ArrayRef
constructors.

The name change indicates that the returned allocation order may contain
reserved registers as has been the case for a while.

In Thumb mode we cannot handle GPR virtual registers, even though some
instructions can. When isel is lowering a CopyFromReg, it should limit
itself to subclasses of getRegClassFor(VT).
