[ARM] Add support for M-profile MVE extension
This patch adds support for the M-profile MVE extension, which includes the
following:
- New M-profile XML feature m-profile-mve
- MVE vector predication status and control register (VPR)
- p0 pseudo register (contained in the VPR)
- q0 ~ q7 pseudo vector registers
- New feature bits
- Documentation update
Pseudo register p0 is the least significant bits of vpr and can be accessed
as $p0 or displayed through $vpr. For more information about the register
layout, please refer to [1].
The q0 ~ q7 registers map back to the d0 ~ d15 registers, two d registers
per q register.
The register dump looks like this:
