When generating IR for default copy-constructors, copy-assignment operators,
move-constructors and move-assignment operators, use memcpy to copy adjacent
POD members.
Previously, classes with one or more Non-POD members would fall back on
element-wise copies for all members, including POD members. This often
generated a lot of IR. Without padding metadata, it wasn't often possible
for the LLVM optimizers to turn the element-wise copies into a memcpy.
This code hasn't yet received any serious tuning. I didn't see any serious
regressions on a self-hosted clang build, or any of the nightly tests, but
I think it's important to get this out in the wild to get more testing.

Use -mno-implicit-float by default for kernel/kext code. <rdar://

Apple's kernel engineers have been expecting this behavior even though
we've never implemented it before, as far as I can tell. In recent months,
clang has gotten better at using vector instructions to optimize memcpy-like
operations, and that has exposed problems when vector/floating-point
instructions are used in kexts that don't support that. This behavior also
matches what Apple's GCC did for PowerPC targets.

For x86 targets, we've been using the -msoft-float option to control passing

now accepted by the driver, this just makes it work for x86 the same as it
does for ARM targets.

Add support for updating LiveIntervals to PHIElimination. If LiveIntervals are
present, it currently verifies them with the MachineVerifier, and this passed
all of the test cases in 'make check' (when accounting for existing verifier
errors). There were some assertion failures in the two-address pass, but they
also happened on code without phis and look like they are caused by different
kill flags from LiveIntervals.
The only part that doesn't work is the critical edge splitting heuristic,
because there isn't currently an efficient way to update LiveIntervals after
splitting an edge. I'll probably start by implementing the slow fallback and
test that it works before tackling the fast path for single-block ranges. The
existing code that updates LiveVariables is fairly slow as it is.
There isn't a command-line option for enabling this; instead, just edit
PHIElimination.cpp to require LiveIntervals.
