Cleaning up LLVM IR mode for Emacs.
I've made a range of improvements to the Emacs mode for LLVM IR.
Most importantly, it changes llvm-mode to inherit from prog-mode. This
means llvm-mode will be treated as a normal programming mode in Emacs,
so many Emacs features will just work. prog-mode is new to Emacs 24,
so I've added an alias to ensure compatibility with Emacs 23 too.
I've changed the mode definition to use define-derived-mode. This
saves us needing to set up local variables ourselves, and saves us
needing to define llvm-mode-map, llvm-mode-abbrev-table,
llvm-mode-map.
I've removed the keybindings to tab-to-tab-stop, center-line and
center-paragraph. This shouldn't be llvm-mode's responsibility, and
the code didn't actually work anyway (since `(not llvm-mode-map)`
always evaluated to `t`, the keybindings were never executed).
I've simplified the syntax-table definition, it's equivalent (e.g. `"`
is treated as string delimiter by default in Emacs). I've added `.` as
a symbol constituent, so functions like `llvm.memset.p0i8.i32` are
recognised as a single symbol. I've also changed `%` to be a symbol
constituent, so users can move between words or symbols at their
choice, rather than conflating the two.
I've fixed regexp for types, which incorrect used `symbol` instead of
`symbols` as an argument to `regexp-opt`. This was causing incorrect
highlighting on lines like `call void @foovoid`.
I've removed string and comment highlighting from
`llvm-font-lock-keywords`. This is already handled by the
syntax-table.
Finally, I've removed the reference to jasmin. That project is long
abandoned and the link 404s. For reference, I've found an old copy of

Replace ScalarEvolution based domain generation
This patch replaces the last legacy part of the domain generation, namely the

thereby assume the absence of infinite loops.

[ADT] Apply a large hammer to StringRef functions: attribute always_inline.
The logic of this follows something Howard does in libc++ and something
I discussed with Chris eons ago -- for a lot of functions, there is
really no benefit to preserving "debug information" by leaving the
out-of-line even in debug builds. This is especially true as we now do
a very good job of preserving most debug information even in the face of
inlining. There are a bunch of methods in StringRef that we are paying
a completely unacceptable amount for with every debug build of every
LLVM developer.
Some day, we should fix Clang/LLVM so that developers can reasonable
use a default of something other than '-O0' and not waste their lives
waiting on *completely* unoptimized code to execute. We should have
a default that doesn't impede debugging while providing at least
plausable performance.
But today is not that day.
So today, I'm applying always_inline to the functions that are really
hurting the critical path for stuff like 'check_llvm'. I'm being very
cautious here, but there are a few other APIs that we really should do
this for as a matter of pragmatism. Hopefully we can rip this out some

with the StringRef::split method when used with a MaxSplit argument
other than '-1' (which nobody really does today, but which should

The spec claimed both to split up to MaxSplit times, but also to append
<= MaxSplit strings to the vector. One of these doesn't make sense.
Given the name "MaxSplit", let's go with it being a max over how many
*splits* occur, which means the max on how many strings get appended is
MaxSplit+1. I'm not actually sure the implementation correctly provided
this logic either, as it used a really opaque loop structure.
The implementation was also playing weird games with nullptr in the data
field to try to rely on a totally opaque hidden property of the split
method that returns a pair. Nasty IMO.
Replace all of this with what is (IMO) simpler code that doesn't use the
pair returning split method, and instead just finds each separator and
appends directly. I think this is a lot easier to read, and it most

[AArch64] Support selecting STNP.
We could go through the load/store optimizer and match STNP where
we would have matched a nontemporal-annotated STP, but that's not
reliable enough, as an opportunistic optimization.
Insetad, we can guarantee emitting STNP, by matching them at ISel.
Since there are no single-input nontemporal stores, we have to
resort to some high-bits-extracting trickery to generate an STNP
from a plain store.
Also, we need to support another, LDP/STP-specific addressing mode,
base + signed scaled 7-bit immediate offset.
For now, only match the base. Let's make it smart separately.

[RewriteStatepointsForGC] Extend base pointer inference to handle insertelement
This change is simply enhancing the existing inference algorithm to handle insertelement instructions by conservatively inserting a new instruction to propagate the vector of associated base pointers. In the process, I'm ripping out the peephole optimizations which mostly helped cover the fact this hadn't been done.
Note that most of the newly inserted nodes will be nearly immediately removed by the post insertion optimization pass introduced in 246718. Arguably, we should be trying harder to avoid the malloc traffic here, but I'd rather get the code correct, then worry about compile time.
Unlike previous extensions of the algorithm to handle more case, I discovered the existing code was causing miscompiles in some cases. In particular, we had an implicit assumption that the peephole covered *all* insert element instructions, so if we had a value directly based on a insert element the peephole didn't cover, we proceeded as if it were a base anyways. Not good. I believe we had the same issue with shufflevector which is why I adjusted the predicate for them as well.

[RewriteStatepointsForGC] Make base pointer inference deterministic
Previously, the base pointer algorithm wasn't deterministic. The core fixed point was (of course), but we were inserting new nodes and optimizing them in an order which was unspecified and variable. We'd somewhat hacked around this for testing by sorting by value name, but that doesn't solve the general determinism problem.
Instead, we can use the order of traversal over the def/use graph to give us a single consistent ordering. Today, this is a DFS order, but the exact order doesn't mater provided it's deterministic for a given input.
(Q: It is safe to rely on a deterministic order of operands right?)
Note that this only fixes the determinism within a single inference step. The inference step is currently invoked many times in a non-deterministic order. That's a future change in the sequence. :)
