6ff3fd8021 Remove TPat. No patterns depend on just isThumb(). Must use either T1Pat (isThumb1Only()) or T2Pat (is Thumb2).

34d4b90554 Many of Daniel's fixes. 
I'm returning the number of bytes actually copied so that the client has some
warning when it reads past the end of the buffer.

I'm keeping the distinction between getByte() and getBytes() for now for
subclasses that use functions like ptrace() on Linux and only have a restricted
interface.  This makes their implementation easier, and subclasses can always
write a one-line implementation of readByte() that uses their custom 
readBytes().

a773ae7a39 Get rid of some more getOpcode calls. 
This also fixes potential problems in ARMBaseInstrInfo routines not recognizing thumb1 instructions when 32-bit and 16-bit instructions mix.

793cbcd529 sink text/data section creation down into the target-specific places that 
should know about them.  PECoff doesn't share these, and I want all sections
to be created by object-file-specific code.

c1b29cb551 fixed incorrect lowering of ISD::SUB node. SUB has only one result value. 
It wasn't caught during tests because we never got a sub generated, (i8 was always getting promoted to int, which in turn was broken into subc/sube). Though the optimizer leaves an i8 sub now.

a6737e21cf Rename tMOVhi2lor to tMOVgpr2tgpr. It's not moving from a high register to a low register. It's moving from a GPR register class to a more restrictive tGPR class. Also change tMOVlor2hir, and tMOVhir2hir.
