This commit adds arm32 Thumb2 code generation for some IR insts.
I have used machinst backend and followed Aarch64 implementation as an example.Floating-point instructions are not supported, because regalloc
does not seem to allow to represent overlapping register classes,
which are needed by VFP/Neon.Another lacking feature is support for I64 and I128 types.
An abi implementation is not complete, however it makes it possible
to run simple clif tests.It may be a first step towards #1173.
This PR contains instruction emission test and clif tests for IR insts.
I don't know well who could review this.

Maybe use x86 or riscv instead?

I believe some of the tests here or in regalloc/pressure.rs use the fact that S, D and Q registers overlap. I am not sure if we can achieve something similar with x86 or risc-v registers.
