ed09087dd3 Correctly size-reduce the t2CMPzrr instruction to tCMPzr when possible. 
tCMPzhir has undefined behavior when both source registers are low registers.

ARM instruction). Add encoding of bits 13 and 11.

0bdf0c05b9 The tLDR instruction wasn't encoded properly: 
<MCInst 2251 <MCOperand Reg:70> <MCOperand Reg:66> <MCOperand Imm:0> <MCOperand Reg:0> <MCOperand Imm:14> <MCOperand Reg:0>>

Notice that the "reg" here is 0, which is an invalid register. Put a check in
the code for this to prevent crashing.

3d2125c9db Enable sibling call optimization of libcalls which are expanded during 
legalization time. Since at legalization time there is no mapping from
SDNode back to the corresponding LLVM instruction and the return
SDNode is target specific, this requires a target hook to check for
eligibility. Only x86 and ARM support this form of sibcall optimization
right now.
