CodeGen incorrectly ignores (assert from APInt) constant index bigger
than 2^64 in getelementptr instruction. This is a test and fix for that.

The PowerPC backend had a number of loads that were marked as canFoldAsLoad
(and I'm partially at fault here for copying around the relevant line of
TableGen definitions without really looking at what it meant). This is not
right; PPC (non-memory) instructions don't support direct memory operands, and
so there is nothing a 'foldable' instruction could be folded into.
Noticed by inspection, no test case.
The one thing we might lose by doing this is ability to fold some loads into
stackmap/patchpoint pseudo-instructions. However, this was untested, and would
not obviously have worked for extending loads, and I'd rather re-add support
for that once it can be tested.

that control, individually, all of the disparate things it was
controlling.
At the same time move a FIXME in the Hexagon port to a new
subtarget function that will enable a user of the machine
scheduler to avoid using the source scheduler for pre-RA-scheduling.
The FIXME would have this removed, but involves either testcase
changes or adding -pre-RA-sched=source to a few testcases.

time. The target independent code was passing in one all the
time and targets weren't checking validity before using. Update
a few calls to pass in a MachineFunction where necessary.

This reverts commit r231957.
IntervalMap currently doesn't support keys more aligned than host pointers
and I've been using it with uint64_t keys. This asserts on some 32bits
systems.
Revert while I work on an IntervalMap generalization.

If a function is going in an unique section (because of -ffunction-sections
for example), putting a jump table in .rodata will keep .rodata alive and
that will keep alive any other function that also has a jump table.
Instead, put the jump table in a unique section that is associated with the
function.

The main issue being fixed here is that APCS targets handling a "byval align N"
parameter with N > 4 were miscounting what objects were where on the stack,
leading to FrameLowering setting the frame pointer incorrectly and clobbering
the stack.
But byval handling had grown over many years, and had multiple layers of cruft
trying to compensate for each other and calculate padding correctly. This only
really needs to be done once, in the HandleByVal function. Elsewhere should
just do what it's told by that call.
I also stripped out unnecessary APCS/AAPCS distinctions (now that Clang emits
byvals with the correct C ABI alignment), which simplified HandleByVal.

Gather the function ranges [low_pc, high_pc) during DIE selection and
store them along with the offset to apply to them to get the linked
addresses.
This is just the data collection part, it comes with no tests. That
information will be used in multiple followup commits to perform the
relocation of line tables and range sections among other things, and
these commits will add tests.

DW_AT_low_pc on functions is taken care of by the relocation processing, but
DW_AT_high_pc and DW_AT_low_pc on other lexical scopes need special handling.

This is a follow-up to r231182. This adds the "vbroadcasti128" instruction
back, but without the intrinsic mapping. Also add a test to check the
instriction encoding.
This is related to rdar://problem/18742778.

Summary:
The generic ELF TargetObjectFile defaults to .ctors, but Linux's
defaults to .init_array by calling InitializeELF with the value of
UseInitArray from TargetMachine. Make NaCl's behavior match.

The CallGraphNode function "addCalledFunction()" asserts that edges are not to intrinsics.
This patch makes sure that the Inliner does not add such an edge to the callgraph.

As of r231908, the test I added in r231902 actually gets run - but I'd
checked in a stale version of the input so it didn't pass. Fix the
input and un-xfail the test.

This causes a crash if the referenced intrinsic was malformed. In this case, we
would already have reported an error on the referenced intrinsic, but then
crashed on the second one when it tried to introspect the first without
error checking.
llvm-svn: 231910
There were also errors in the CHECK line which I fixed and the test
doesn't actually pass as the "100" is in the wrong line. Not sure
whether this is a test failure or a coverage failure so making the test
XFAIL for now.
