major win on 253.perlbmk on ARM Darwin.  I expect it
to be a good heuristic in general, but it's possible
some things will regress; I'll be watching.

Remove PCHReader::getStream(), it was unused. Inline PCHReader::getDelsCursor() into its sole caller and remove it. This reduces the attack surface of multiple PCH files towards code outside the PCH implementation.

Teach computeRegisterProperties() to compute "representative" register class for legal value types. A "representative" register class is the largest legal super-reg register class for a value type. e.g. On i386, GR32 is the rep register class for i8 / i16 / i32; on x86_64 it would be GR64.

This property will be used by the register pressure tracking instruction scheduler.
