95131fcb67 Use the return value of getMagicNumber instead of using a 
separate canRead() call.

02d5824266 Don't bother clearing the Magic string when the magic number 
can't be read, since it isn't cleared on other error paths.

130de9c0b4 Don't bother checking canRead() before calling getMagicNumber(); 
getMagicNumber() does its own error checking.

ca561ffcf3 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.
