f1b41dd38d Record landing pads with a SmallSetVector to avoid multiple entries. 
There may be many invokes that share one landing pad, and the previous code
would record the landing pad once for each invoke.  Besides the wasted
effort, a pair of volatile loads gets inserted every time the landing pad is
processed.  The rest of the code can get optimized away when a landing pad
is processed repeatedly, but the volatile loads remain, resulting in code like:

20c918dfed Update the SP in the SjLj jmpbuf whenever it changes. <rdar://problem/10444602> 
This same basic code was in the older version of the SjLj exception handling,
but it was removed in the recent revisions to that code.  It needs to be there.

eaab6ef6eb Fix ARM SjLj-EH dispatch setup code. <rdar://problem/10444602> 
The EmitBasePointerRecalculation function has 2 problems, one minor and one
fatal.  The minor problem is that it inserts the code at the setjmp
instead of in the dispatch block.  The fatal problem is that at the point
where this code runs, we don't know whether there will be a base pointer,
so the entire function is a no-op.  The base pointer recalculation needs to
be handled as it was before, by inserting a pseudo instruction that gets
expanded late.

Most of the support for the old approach is still here, but it no longer
has any connection to the eh_sjlj_dispatchsetup intrinsic.  Clean up the
parts related to the intrinsic and just generate the pseudo instruction
directly.

3805d85e38 Enable -widen-vmovs by default. 
This will widen 32-bit register vmov instructions to 64-bit when
possible.  The 64-bit vmovd instructions can then be translated to NEON
vorr instructions by the execution dependency fix pass.

The copies are only widened if they are marked as clobbering the whole
D-register.

22b34cce4d GEPs with all zero indices are trivially coalesced by fast-isel. For example, 
%arrayidx135 = getelementptr inbounds [4 x [4 x [4 x [4 x i32]]]]* %M0, i32 0, i64 0
%arrayidx136 = getelementptr inbounds [4 x [4 x [4 x i32]]]* %arrayidx135, i32 0, i64 %idxprom134

Prior to this commit, the GEP instruction that defines %arrayidx136 thought that 
%arrayidx135 was a trivial kill.  The GEP that defines %arrayidx135 doesn't 
generate any code and thus %M0 gets folded into the second GEP.  Thus, we need
to look through GEPs with all zero indices.

e43862b6a6 ARM assembly parsing for register range syntax for VLD/VST register lists. 
For example,
vld1.f64 {d2-d5}, [r2,:128]!

Should be equivalent to:
vld1.f64 {d2,d3,d4,d5}, [r2,:128]!

It's not documented syntax in the ARM ARM, but it is consistent with what's
accepted for VLDM/VSTM and is unambiguous in meaning, so it's a good thing to
support.
