PAL Metadata 3.0 introduces an explicit structure in metadata for the
programmable registers written out by the compiler backend.
Rather than using opaque registers which can change between different
architectures and requires encoding the bitfield information in the backend,
which may change between versions.
This is the initial minimal implementation that enables the use of PAL Metadata
3.0.
The change itself should be NFC for non-PAL, although the way RSRC2 register is
handled has been changed slightly.
The test is fairly minimal, but checks that the metadata format looks as
expected and verifies a couple of special cases such as tgid_[xyz]_en handling
and PsInputAddr/Ena which also change to explicit fields.

Account and report agprs separately on gfx908. Other targets
do not change the reporting.

We had couple places which still return 10 as a maximum
occupancy. Fixed.
Also print comment about occupancy as compiler see it.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
