[test] Add preliminary FP tests for OP.<dt> <Dd>, <Dn>, <Dm>
Add floating point tests for instructions taking three D registers as
operands.
We have assembler tests for the following instrutions with F32 and F64:
- VABD
- VADD
- VCEQ
- VCGE
- VCGT
- VCLE
- VCLT
- VMAX
- VMIN
- VPADD
- VPMAX
- VPMIN
- VSUB
And simulation (as in execution on hardware) for the following instructions,
only with F64 as a datatype.
- VADD
- VSUB

Remove implicit 64 to 32 bit narrowing
This patch fixes cases of implicit 64 to 32 bit narrowing. The issue is
that `CodeBuffer` represents code offsets with `ptrdiff_t`, which will
be 64 bit on a 64 bit system. However, we want to support generating 32
bit code from a 64 bit program, therefore the 32 bit part of VIXL works
with `int32_t` for code offsets. We had implicit conversions happening
due to this.
We solve this by explicitely casting to `int32_t` in the AArch32
assembler when calling `GetCursorOffset`. If you are working with the
`CodeBuffer` directly, you are dealing with a code buffer on the host
and so will work with offsets as `ptrdiff_t`. But, when working with the
AArch32 assembler itself you will get offsets as `int32_t`. The
assembler is in charge of checking that the offsets it gets from the
code buffer fit into `int32_t`.
Additionally, we had narrowing cases when generally wrapping host
pointers into an Operand. This can only work if the pointer fits into 32
bits. This patch introduces a Operand::From() factory method that can be
used for converting any integral or pointer type to an immediate
operand.

Add assembler, macro-assembler and disassembler support for AArch32
Add support for the A32 and T32 instruction set architectures in
seperate a32 directories.
Note that this commit introduces aarch32 and aarch64 namespaces so
existing client code will need to be adjusted.
Refer to doc/getting-started-a32.md for an introduction.
