32-bit wide version by adding the .w suffix.

7ece6027a9 XFAIL for now. If someone with access to an ARM/Linux host wants to have a look
that would be great. They're ARM JIT failures, so without that, it's tough.

ee3a428e0f This test dates from the time when llvm-gcc had problems if two types were
named the same, so it had to qualify type names according to the enclosing
scope to ensure uniqueness.  This is no longer needed for correctness (though
it may be helpful when reading the IR), so this test has lost its importance.
Zap it because dragonegg will never be able to produce the qualified type name
since modern gcc zaps language specific info (such as whether a type is nested
inside another - needed to get X::Y here) before dragonegg is reached.

3d2125c9db Enable sibling call optimization of libcalls which are expanded during
legalization time. Since at legalization time there is no mapping from
SDNode back to the corresponding LLVM instruction and the return
SDNode is target specific, this requires a target hook to check for
eligibility. Only x86 and ARM support this form of sibcall optimization
right now.

certainly be made more generic. But it does allow us to parse something like:

          ldr     r3, [r2, r4]

correctly in Thumb mode.

cf82dc376a Rewrite the main DSE loop to be written in terms of reasoning
about pairs of AA::Location's instead of looking for MemDep's
"Def" predicate.  This is more powerful and general, handling
memset/memcpy/store all uniformly, and implementing PR8701 and
probably obsoleting parts of memcpyoptimizer.

This also fixes an obscure bug with init.trampoline and i8
stores, but I'm not surprised it hasn't been hit yet.  Enhancing
init.trampoline to carry the size that it stores would allow
DSE to be much more aggressive about optimizing them.
