Rework constant expr and array handling for objectsize instcombining.
...
Fix bugs where we would compute out of bounds as in bounds, and where
we couldn't know that the linker could override the size of an array.
Add a few new testcases, change existing testcase to use a private
global array instead of extern.

Indirect tail call has to go through a call preserved register since it's after callee register pops. X86 isel lowering is using EAX / R11 and it was somehow adding that to function live out. That prevented the real function return register from being added to the function live out list and bad things happen.
...
This fixes 483.xalancbmk (with tail call opt).

Adjust the heuristics used to decide when SROA is likely to be profitable.
...
The SRThreshold value makes perfect sense for checking if an entire aggregate
should be promoted to a scalar integer, but it is not so good for splitting
an aggregate into its separate elements. A struct may contain a large embedded
array along with some scalar fields that would benefit from being split apart
by SROA. Even if the total aggregate size is large, it may still be good to
perform SROA. Thus, the most important piece of this patch is simply moving
the aggregate size comparison vs. SRThreshold so that it guards only the
aggregate promotion.
We have also been checking the number of elements to decide if an aggregate
should be split up. The limit of "SRThreshold/4" seemed rather arbitrary,
and I don't think it's very useful to derive this limit from SRThreshold
anyway. I've collected some data showing that the current default limit of
32 (since SRThreshold defaults to 128) is a reasonable cutoff for struct
types. One thing suggested by the data is that distinguishing between structs
and arrays might be useful. There are (obviously) a lot more large arrays
than large structs (as measured by the number of elements and not the total
size -- a large array inside a struct still counts as a single element given
the way we do SROA right now). Out of 8377 arrays where we successfully
performed SROA while compiling a large set of benchmarks, only 16 of them had
more than 8 elements. And, for those 16 arrays, it's not at all clear that
SROA was actually beneficial. So, to offset the compile time cost of
investigating more large structs for SROA, the patch lowers the limit on array
elements to 8.
This fixes Apple Radar 7563690.

This test case is different subset of the full auto generated test case, and a

reassemble to the same instruction. It is useful as we bring up the parser and

MC/X86 AsmParser: Handle absolute memory operands correctly. We were doing
...
something totally broken and parsing them as immediates, but the .td file also
had the wrong match class so things sortof worked. Except, that is, that we
would parse
movl $0, %eax
as
movl 0, %eax
Feel free to guess how well that worked.

Keep iterating over all uses when meeting a phi node in AllUsesOfValueWillTrapIfNull().
...
This bug was exposed by my inliner cost changes in r94615, and caused failures
of lencod on most architectures when building with LTO.
This patch fixes lencod and 464.h264ref on x86-64 (and likely others).

MC/X86: Add a nice X86 assembler matcher test case from Kevin Enderby.
...
- This test case is auto generated, and has been verified to round-trip
correctly through llvm-mc by checking the assembled .o file before and after
piping through llvm-mc. It will be extended over time as the matcher grows
support for more instructions.

Modified encoding bits specification for VFP instructions. In particular, the D

Preserve load alignment in instcombine transformations. I've been unable to
...
create a testcase where this matters. The select+load transformation only
occurs when isSafeToLoadUnconditionally is true, and in those situations,
instcombine also changes the underlying objects to be aligned. This seems
like a good idea regardless, and I've verified that it doesn't pessimize
the subsequent realignment.
