[MCJIT] Add options to llvm-rtdyld to describe a phony target address space for
use in -verify mode.
This patch adds three hidden command line options to llvm-rtdyld:
-target-addr-start <start-addr> : Specify the start of the virtual address
space on the phony target.
-target-addr-end <end-addr> : Specify the end of the virtual address space
on the phony target.
-target-section-sep <sep> : Specify the separation (in bytes) between the
end of one section and the start of the next.
These options automatically default to sane values for the target platform. In
particular, they allow narrow (e.g. 32-bit, 16-bit) targets to be tested from
wider (e.g. 64-bit, 32-bit) hosts without overflowing pointers.
The section separation option defaults to zero, but can be set to a large number
(e.g. 1 << 32) to force large separations between sections in order to
stress-test large-code-model code.

Bitcode: Serialize (and recover) use-list order
Predict and serialize use-list order in bitcode. This makes the option
`-preserve-bc-use-list-order` work *most* of the time, but this is still
experimental.
- Builds a full value-table up front in the writer, sets up a list of
use-list orders to write out, and discards the table. This is a
simpler first step than determining the order from the various
overlapping IDs of values on-the-fly.
- The shuffles stored in the use-list order list have an unnecessarily
large memory footprint.
- `blockaddress` expressions cause functions to be materialized
out-of-order. For now I've ignored this problem, so use-list orders
will be wrong for constants used by functions that have block
addresses taken. There are a couple of ways to fix this, but I
don't have a concrete plan yet.
- When materializing functions lazily, the use-lists for constants
will not be correct. This use case is out of scope: what should the
use-list order be, if it's incomplete?

[SDAG] Add DEBUG logging to the legalizer, fixing a "bug" found by
inspection in the proccess, and shuffle the logging in the DAG combiner
around a bit.
With this it is much easier to follow what the legalizer is doing. It
should even accurately present most of the strange legalization
operations where a single node is replaced by multiple nodes, etc. There
is still some information lost (we log SDNodes not SDValues so we don't
log which result is used for which thing), but I think this is much
closer to a usable system. Notably, this will make it *much* more
apparant when legalization is actually happening inside the combiner, or
when there is a cycle caused by interactions of the legalizer and the
combiner.
The "bug" I fixed here I'm not sure is remotely possible to trigger. We
were only adding one of the nodes in a replacement to the updated set
rather than all of the nodes in the replacement. Realistically, the
worst result of this are nodes not getting back onto the worklist in the
DAG combiner. I doubt it is possible to trigger this today, and
I certainly don't have any ideas about how, but this at least brings the
code into alignment with the principled operation of the routine.

[PowerPC] Support ELFv1/ELFv2 ABI selection via features
While LLVM now supports both ELFv1 and ELFv2 ABIs, their use is currently
hard-coded via the target triple: powerpc64-linux is always ELFv1, while
powerpc64le-linux is always ELFv2.
These are of course the most common scenarios, but in principle it is
possible to support the ELFv2 ABI on big-endian or the ELFv1 ABI on
little-endian systems (and GCC does support that), and there are some
special use cases for that (e.g. certain Linux kernel versions could
only be built using ELFv1 on LE).
This patch implements the LLVM side of supporting this. As precedent
on other platforms suggests, ABI options are passed to the back-end as
features. Thus, this patch implements two features "elfv1" and "elfv2"
that select the desired ABI if present. (If not, the LLVM uses the
same default rules as now.)

ARM: correct handling of features in arch_extension
The subtarget information is the ultimate source of truth for the feature set
that is enabled at this point. We would previously not propagate the feature
information to the subtarget. While this worked for the most part (features
would be enabled/disabled as requested), if another operation that changed the
feature bits was encountered (such as a mode switch via a .arm or .thumb
directive), we would end up resetting the behaviour of the architectural
extensions.
Handling this properly requires a slightly more complicated handling. We need
to check if the feature is now being toggled. If so, only then do we toggle the
features. In return, we no longer have to calculate the feature bits ourselves.
The test changes are mostly to the diagnosis, which is now more uniform (a nice
side effect!). Add an additional test to ensure that we handle this case
properly.
Thanks to Nico Weber for alerting me to this issue!

ARM: convert loop to range based
Convert a loop to use range based iteration. Rename structure members to help
naming, and make structure definition anonymous. NFC.

Add alignment value to allowsUnalignedMemoryAccess
Rename to allowsMisalignedMemoryAccess.
On R600, 8 and 16 byte accesses are mostly OK with 4-byte alignment,
and don't need to be split into multiple accesses. Vector loads with
an alignment of the element type are not uncommon in OpenCL code.
