linkage: this linkage type only applies to declarations,
but ODR is only relevant to globals with definitions.

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.

smarter about C-ish syntax, and supports the cinoptions
variable. Set cinoptions to suppress the extra indentation
for switch case labels.

* Fixed cursors in terminal by setting nocompatible (sorry, vi users)
* Enable syntax highlighting so that this file can stand on its own
* Highlight trailing whitespace
* Fixed commands to delete trailing whitespaces and convert tabs to spaces

llvm.vim and tablegen.vim
* Removed trailing whitespace, as it's now very visible

- defm and multiclass
- imbricatable multiline C style comment
- FIXME/TODO highlight in comment
- binary and hexadecimal number
- code using [{ }] is no highlighted as special (perhaps not the best
choice)
