likely not a bitcode file at all, rather than being a bitcode file which
is truncated. Check for this case and issue a more relevant error message.

-print-before=<Pass Name>
Dump IR before running pass <Pass Name>.
-print-before-all
Dump IR before running each pass.
-print-after-all
Dump IR after running each pass.
These are helpful when tracking down a miscompilation. It is easy to
get IR dumps and do diffs on them, etc.
To make this work well, add a new getPrinterPass API to Pass so that
each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
suitable for dumping out the kind of object the Pass works on.

- Do not try to infer GV alignment unless its type is sized. It's not possible to infer alignment if it has opaque type.

- Use a RAII object to close the FD.
- Use sys::StrError instead of thread-unsafe strerror calls.
- Recover gracefully if read returns zero. This works around an issue on
DragonFlyBSD where /dev/null has an st_size of 136 but we can't read 136 bytes
from it.

that allows full mutation.
Adapt some call sites in analyses to employ ImmutableCallSite.

of raw mdnodes. This allows frontends to specify debug
locations without ever creating an MDNode for the DILocation.
This requires a corresponding clang/llvm-gcc change which
I'll try to commit as simultaneously as possible.

1. Makes it possible to lower with floating point loads and stores.
2. Avoid unaligned loads / stores unless it's fast.
3. Fix some memcpy lowering logic bug related to when to optimize a
load from constant string into a constant.
4. Adjust x86 memcpy lowering threshold to make it more sane.
5. Fix x86 target hook so it uses vector and floating point memory
ops more effectively.

being a TrackingVH<MDNode> to a NewDebugLoc, shrinking
sizeof(Instruction) a lot, and providing clients the ability
to deal with locations in terms of NewDebugLoc instead of
having to deal with Metadata. This is still fully compatible
with all clients that *do* use MDNodes for everything of
course.
No functionality change.

and will replace the 'DbgInfo' member in Instruction.
The benefit of NewDebugLoc is that it is compact (8 bytes vs 12/24
bytes for the DbgInfo member in Instruction on a 32/64 bit system),
it means that we will end up not having to allocate MDNodes to
represent the "DILocations" in common cases of -O0 -g, and it is
much more efficient to get things out of than the MDNode.

* Set the "DestA" and "DestB" according to how they're understood by the
method. I.e., if one or both of them should point to the "fall through" block,
then point to the fall through block.
* Improve the loop that removes superfluous edges to be more understandable.
