Peter Collingbourne 10039c02ea LTO: introduce object file-based on-disk module format.
This format is simply a regular object file with the bitcode stored in a
section named ".llvmbc", plus any number of other (non-allocated) sections.

One immediate use case for this is to accommodate compilation processes
which expect the object file to contain metadata in non-allocated sections,
such as the ".go_export" section used by some Go compilers [1], although I
imagine that in the future we could consider compiling parts of the module
(such as large non-inlinable functions) directly into the object file to
improve LTO efficiency.

Eli Bendersky 5d5e18da3e Rename loop unrolling and loop vectorizer metadata to have a common prefix.
[LLVM part]

These patches rename the loop unrolling and loop vectorizer metadata
such that they have a common 'llvm.loop.' prefix.  Metadata name
changes:

llvm.vectorizer.* => llvm.loop.vectorizer.*
llvm.loopunroll.* => llvm.loop.unroll.*

This was a suggestion from an earlier review
(http://reviews.llvm.org/D4090) which added the loop unrolling
metadata. 

Patch by Mark Heffernan.

Rafael Espindola 2a2a0973b8 Use pipefail when available.
This change makes test with RUN lines like
RUN: opt ... | FileCheck

fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.

Pipefail is used when the shell supports it or when using the internal
python based tester.

Sean Silva 1eab30dc17 docs: Nuke the old release notes.
This change also removes a bunch of boilerplate and stuffing which made
it unnecessarily hard to navigate and see the comparatively miniscule
actual content that was added to this document during the 3.2
development period (or maybe even sticking around from earlier
releases...).

The new organization (a flat list) optimizes for making it easy for
people who know about changes to add them to the document.  It's
completely trivial for anyone with basic knowledge of LLVM to come in
later (such as when preparing for the actual release) and cluster any
changes into logical groups. However, I have left some comments
indicating how to add larger descriptions, if someone is feeling
adventurous ;)

Hopefully this organization will highlight how little effort is being
put into producing accurate, high-quality release notes, prompting a
corresponding improvement for the 3.3 release.

I have preserved the changes to this document that are not present
in the 3.2 release notes. There were only two... I'm pretty sure we've
been busier than that... (version control shows +213347/-173656 raw
lines just in the LLVM repo since the 3.2 release).
