This reverts commit r287684
Objections on the review thread had not been addressed to
prior to commit. I asked the committer to revert, but i expect they
are gone for the US holiday or something.

This patch adds Cortex-R52, the new ARM real-time processor, to LLVM.
Cortex-R52 implements the ARMv8-R architecture.

Summary:
For AMDGPU, we have been using the operating system component of the triple
for specifying the low-level runtime that is being used. The rationale for
this is that the host operating system (e.g. Linux) is irrelevant for GPU code,
since its execution enviroment will be mostly controled by the low-level runtime
being used to execute the code.
In most cases, higher level languages have their own runtime which is
implemented on top of the low-level runtime. The kernel ABIs of each
language mostly depend on the low-level runtime, but there may be some
slight differences between languages. OpenCL for example, may append
additional arguments to the kernel in order to pass values like global
offsets or buffers for printf. OpenMP, HCC, or other languages may want
to add their own values which differ from OpenCL.
The reason for adding a new opencl environment type is to make it possible for the backend
to distinguish between the ABIs of the higher-level languages and handle them correctly.
It seems cleaner to use the enviroment component for this rather than creating a new
OS type for every combination of low-level runtime / high-level language.

Since these are named nvvm_* rather than nvptx_*, we also need to
update getArchTypePrefix. It's a bit unusual for getArchTypePrefix not
to match the backend name, but I think this fits the intent of the
function in this case.

Summary:
Add renderscript32 and renderscript64 ArchTypes. This is to configure
the ABI requirement on 32-bit RenderScript that 'long' types have 64-bit
size and alignment. 64-bit RenderScript is the same as AArch64, but is
added here for completeness.

This allows us to query about the endianness without having to
look at DataLayout. The API will be used (and tested) in lld,
in order to find out the endianness of BitcodeFiles.
Briefly discussed with Rafael.

As support expands to more runtimes, we'll need to
distinguish between more than just HSA and unknown.
This also lets us stop using unknown everywhere.

Change Triple::get32BitArchVariant to return arm/armeb as the 32bit
variant of aarch64/aarch64_be and do the same change for the oppoiste
direction in Triple::get64BitArchVariant.

InitMCObjectFileInfo was trying to override the triple in awkward ways.
For example, a triple specifying COFF but not Windows was forced as ELF.
This makes it easy for internal invariants to get violated, such as
those which triggered PR25912.
This fixes PR25912.
