Jim Grosbach ce18d7ebb5 Encode condition code for Thumb1 conditional branch instruction.

Jim Grosbach 5bae054f07 Correctly size-reduce the t2CMPzrr instruction to tCMPzr when possible.
tCMPzhir has undefined behavior when both source registers are low registers.

Jim Grosbach a09cbbeef5 Match pattern operand names to expected encoding field names. This corrects the
operand encoding ordering of the instruction.

Jim Grosbach e4fee20498 Remove incorrect BL target encoding (it's similar to, but not the same as the
ARM instruction). Add encoding of bits 13 and 11.

Nate Begeman a6c55a3195 Revert this change since it breaks a couple of the AVX tests.
I'm unclear if the tests are actually correct or not, but reverting for now.

Nate Begeman 842455332f Remove SSE1-4 disable when AVX is enabled. While this may be useful for development,
it completely breaks scalar fp in xmm regs when AVX is enabled.

Rafael Espindola 57ab708bdd Try to resolve symbol differences early, and if successful create a plain
data fragment. This reduces the time to assemble the test in 8711 from 60s to
54s.

Bill Wendling f0b36a3cfd 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.

Duncan Sands c4fb38b821 I don't think it makes any sense to assert that the target supports SSE3 here.
The user (i.e. whoever generated a call to the intrinsic in the first place) is
essentially asking for a particular instruction to be placed in the assembler.
If that instruction won't execute on the target machine, that's their problem
not ours.  Two buildbots with processors that don't support SSE3 were barfing
on the apm.ll test in CodeGen/X86 because of this assertion.
