Dan Gohman ece4bf5148 Use the return value of getMagicNumber instead of using a 
separate canRead() call.

Dan Gohman 78d1e84521 Don't bother clearing the Magic string when the magic number 
can't be read, since it isn't cleared on other error paths.

Dan Gohman 16f4bd8140 Don't bother checking canRead() before calling getMagicNumber(); 
getMagicNumber() does its own error checking.

Dan Gohman 52c2738324 Eliminate the use of PriorityQueue and just use a std::vector, 
implementing pop with a linear search for a "best" element. The priority
queue was a neat idea, but in practice the comparison functions depend
on dynamic information.

Jakob Stoklund Olesen 7de379467e Replace the SubRegSet tablegen class with a less error-prone mechanism. 
A Register with subregisters must also provide SubRegIndices for adressing the
subregisters. TableGen automatically inherits indices for sub-subregisters to
minimize typing.

CompositeIndices may be specified for the weirder cases such as the XMM sub_sd
index that returns the same register, and ARM NEON Q registers where both D
subregs have ssub_0 and ssub_1 sub-subregs.

It is now required that all subregisters are named by an index, and a future
patch will also require inherited subregisters to be named. This is necessary to
allow composite subregister indices to be reduced to a single index.
