Now that SrcBits and DestBits always represent the primitive size, rather
...
than either the primitive size or the element primitive size (in the case
of vectors), simplify the vector logic. No functionality change. There
is some distracting churn in the patch because I lined up comments better
while there - sorry about that.

Tighten up checking of the validity of casts. (1) The IR parser would
...
happily accept things like "sext <2 x i32> to <999 x i64>". It would
also accept "sext <2 x i32> to i64", though the verifier would catch
that later. Fixed by having castIsValid check that vector lengths match
except when doing a bitcast. (2) When creating a cast instruction, check
that the cast is valid (this was already done when creating constexpr
casts). While there, replace getScalarSizeInBits (used to allow more
vector casts) with getPrimitiveSizeInBits in getCastOpcode and isCastable
since vector to vector casts are now handled explicitly by passing to the
element types; i.e. this bit should result in no functional change.

Teach getCastOpcode about element-by-element vector casts. For example, "trunc"
...
can be used to turn a <4 x i64> into a <4 x i32> but getCastOpcode would assert
if you passed these types to it. Note that this strictly extends the previous
functionality: if getCastOpcode previously accepted two vector types (i.e. didn't
assert) then it still will and returns the same opcode (BitCast). That's because
before it would only accept vectors with the same bitwidth, and the new code only
touches vectors with the same length. However if two vectors have both the same
bitwidth and the same length then their element types have the same bitwidth, so
the new logic will return BitCast as before.

Add support for plugins add passes to the default set of passes. The standard set of passes used by front ends can now be modified by LLVM plugins, without needing to modify any front ends.
...
Still to do:
- Allow replacing / removing passes (infrastructure there, just needs an infrastructure exposed)
- Defining sets of passes to be added or removed as a group
- Extending the support to allow user-defined groups of optimisations
- Allow plugins to be specified for loading automatically (e.g. from plugins.conf or some similar mechanism)

as intrinsics vmull* + add / sub. Also note the isel optimizations for catching

Add a special streamer to libLTO that just records symbols definitions and

uses.
The result produced by the streamer is used to give the linker more accurate
information and to add to llvm.compiler.used. The second improvement removes
the need for the user to add __attribute__((used)) to functions only used in
inline asm. The first one lets us build firefox with LTO on Darwin :-)
