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
the project here:

llvm-mode was previously confused when variable names contained keywords.
This changes ensures that keywords are only highlighted when they're standalone.

In llvm-mode, with electric-pair-mode turned on, typing a literal '['
would print out '[[', and '(' would print a '(('. This was a very
annoying bug caused by overzealous syntax-table entries: the parens are
already part of the '(' and ')' class by default. Fix this.
While at it, notice that i32, i64, i1 etc. are not font-locked despite a
clear intent to do so. The issue is that regexp-opt doesn't accept
regular expressions. So, spell out the common literal integers with
different widths.

Propagate whether `MDNode`s are 'distinct' through the other types of IR
(assembly and bitcode). This adds the `distinct` keyword to assembly.
Currently, no one actually calls `MDNode::getDistinct()`, so these nodes
only get created for:
- self-references, which are never uniqued, and
- nodes whose operands are replaced that hit a uniquing collision.
The concept of distinct nodes is still not quite first-class, since
distinct-ness doesn't yet survive across `MapMetadata()`.
Part of PR22111.

* Both files have valid package headers and footers (you can verify
with M-x checkdoc).
* Fixed style warnings generated by checkdoc.
* Fixed a byte-compiler warning in llvm-mode.el.
* Ensure that the modes are autoloaded, so users do not need to
(require 'llvm-mode) to use them.

Remove setting of default style, this way is not recommended and
means that all the settings have to be duplicated to demonstrate the
c-add-style method which is a much better way of doing it.
Remove the modified date as it is better stored in SVN.
Tweak a few style parameters to make them conform to the actual LLVM
style.

Implement `uselistorder` and `uselistorder_bb` assembly directives,
which allow the use-list order to be recovered when round-tripping to
assembly.
This is the bulk of PR20515.

Add some data structures to represent for loops. These will be
referenced during object processing to do any needed iteration and
instantiation.
Add foreach keyword support to the lexer.
Add a mode to indicate that we're parsing a foreach loop. This allows
the value parser to early-out when processing the foreach value list.
Add a routine to parse foreach iteration declarations. This is
separate from ParseDeclaration because the type of the named value
(the iterator) doesn't match the type of the initializer value (the
value list). It also needs to add two values to the foreach record:
the iterator and the value list.
Add parsing support for foreach.
Add the code to process foreach loops and create defs based
on iterator values.
Allow foreach loops to be matched at the top level.
When parsing an IDValue check if it is a foreach loop iterator for one
of the active loops. If so, return a VarInit for it.
Add Emacs keyword support for foreach.
Add VIM keyword support for foreach.
Add tests to check foreach operation.
Add TableGen documentation for foreach.
Support foreach with multiple objects.
Support non-braced foreach body with one object.
Do not require types for the foreach declaration. Assume the iterator
type from the iteration list element type.

Multidefs are a bit unwieldy and incomplete. Remove them in favor of
another mechanism, probably for loops.

and extern_weak_odr. These are the same as the non-odr versions,
except that they indicate that the global will only be overridden
by an *equivalent* global. In C, a function with weak linkage can
be overridden by a function which behaves completely differently.
This means that IP passes have to skip weak functions, since any
deductions made from the function definition might be wrong, since
the definition could be replaced by something completely different
at link time. This is not allowed in C++, thanks to the ODR
(One-Definition-Rule): if a function is replaced by another at
link-time, then the new function must be the same as the original
function. If a language knows that a function or other global can
only be overridden by an equivalent global, it can give it the
weak_odr linkage type, and the optimizers will understand that it
is alright to make deductions based on the function body. The
code generators on the other hand map weak and weak_odr linkage
to the same thing.

they appear in words. This would cause things like the "128" in "VR128"
to be highlighted. This patch fixes the highlighting by only recognizing
constants when they have word breaks around them.'
