ae3a0be92e Split the Add, Sub, and Mul instruction opcodes into separate
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

4dc2b39bf8 It makes no sense to have a ODR version of common
linkage, so remove it.

5f4ee1fc5d Remove the one-definition-rule version of extern_weak
linkage: this linkage type only applies to declarations,
but ODR is only relevant to globals with definitions.

667d4b8de6 Introduce new linkage types linkonce_odr, weak_odr, common_odr
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.

adf4e4d06a vimrc
* 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
