The exit-on-error flag on the many_args1.ll test is needed to avoid an
unreachable in BPFTargetLowering::LowerCall. We can also avoid it by ignoring
any superfluous arguments to the call (i.e. any arguments after the first 5).
Fixes PR27766.

v2 of r270419

This patch reverts r270419 because it broke a lot of buildbots,
mostly Windows. We'd like help in investigating the issues, but
for now, it should stay out.

This code should have been with the previous check-in (r270417) and prevents the DelaySlotFiller pass being utilized in functions where the erratum fix has been applied as this will break the run-time code.

Due to an erratum in some versions of LEON, we must insert a NOP after any LD or LDF instruction to ensure the processor has time to load the value correctly before using it. This pass will implement that erratum fix.
The code will have no effect for other Sparc, but non-LEON processors.

If TheModule is declared before LLVMContext then it will be destructed after it,
crashing when it tries to deregister itself from the destructed context.

This isn't the complete fix, but it handles the trivial examples of duplicate vzero* ops in PR27823:
https://llvm.org/bugs/show_bug.cgi?id=27823
...and amusingly, the bogus cases already exist as regression tests, so let's take this baby step.
We'll need to do more in the general case where there's legitimate AVX usage in the function + there's
already a vzero in the code.

We could try harder to handle non-splat vector constants too,
but that seems much rarer to me.
Note that the div test isn't resolved because there's a check
for isIntegerTy() guarding that transform.

This fixes a bug introduced in:
r262115 - CodeGen: Take MachineInstr& in SlotIndexes and LiveIntervals, NFC
The iterator End here might == MBB->end(), and so we can't unconditionally
dereference it. This often goes unnoticed (I don't have a test case that always
crashes, and ASAN does not catch it either) because the function call arguments are
turned right back into iterators. MachineInstrBundleIterator's constructor,
however, does have an assert which might randomly fire.

Main problem here was that SHF_COMPRESSED has the same value with
XCORE_SHF_CP_SECTION, which was included as standart (common) flag.
As far I understand xCore is a family of controllers and it that
means it's constant should be processed separately,
only if e_machine == EM_XCORE, otherwise llvm-readobj would output
different constants twice for compressed section:
Flags [
..
SHF_COMPRESSED (0x800)
..
XCORE_SHF_CP_SECTION (0x800)
..
]
what probably does not make sence if you're not working with xcore file.
