llvm-isel-fuzzer: Weak function invoke the ire of PE/COFF
It's non-trivial to use weak symbols in a cross platform way (See
sanitizer_win_defs.h in compiler-rt), and doing it naively like we
have here causes some build failures:
http://lab.llvm.org:8011/builders/clang-with-thin-lto-windows/builds/1260

this very trivial dummy fuzzer driver, we can just rely on the fact
that we know which hooks any given fuzz target implements and forward
declare a normal symbol.

LiveIntervalAnalysis: Fix alias regunit reserved definition
A register in CodeGen can be marked as reserved: In that case we
consider the register always live and do not use (or rather ignore)
kill/dead/undef operand flags.
LiveIntervalAnalysis however tracks liveness per register unit (not per
register). We already needed adjustments for this in r292871 to deal
with super/sub registers. However I did not look at aliased register
there. Looking at ARM:
FPSCR (regunits FPSCR, FPSCR~FPSCR_NZCV) aliases with FPSCR_NZCV
(regunits FPSCR_NZCV, FPSCR~FPSCR_NZCV) hence they share a register unit
(FPSCR~FPSCR_NZCV) that represents the aliased parts of the registers.
This shared register unit was previously considered non-reserved,
however given that we uses of the reserved FPSCR potentially violate
some rules (like uses without defs) we should make FPSCR~FPSCR_NZCV
reserved too and stop tracking liveness for it.
This patch:
- Defines a register unit as reserved when: At least for one root
register, the root register and all its super registers are reserved.
- Adjust LiveIntervals::computeRegUnitRange() for new reserved
definition.
- Add MachineRegisterInfo::isReservedRegUnit() to have a canonical way
of testing.
- Stop computing LiveRanges for reserved register units in HMEditor even
with UpdateFlags enabled.
- Skip verification of uses of reserved reg units in the machine
verifier (this usually didn't happen because there would be no cached
liverange but there is no guarantee for that and I would run into this
case before the HMEditor tweak, so may as well fix the verifier too).
Note that this should only affect ARMs FPSCR/FPSCR_NZCV registers today;
aliased registers are rarely used, the only other cases are hexagons
P0-P3/P3_0 and C8/USR pairs which are not mixing reserved/non-reserved
registers in an alias.

[SCEV] Add URem support to SCEV
In LLVM IR the following code:
%r = urem <ty> %t, %b
is equivalent to
%q = udiv <ty> %t, %b
%s = mul <ty> nuw %q, %b
%r = sub <ty> nuw %t, %q ; (t / b) * b + (t % b) = t
As UDiv, Mul and Sub are already supported by SCEV, URem can be implemented
with minimal effort using that relation:
%r --> (-%b * (%t /u %b)) + %t
We implement two special cases:
- if %b is 1, the result is always 0
- if %b is a power-of-two, we produce a zext/trunc based expression instead
That is, the following code:
%r = urem i32 %t, 65536
Produces:
%r --> (zext i16 (trunc i32 %a to i16) to i32)
Note that while this helps get a tighter bound on the range analysis and the
known-bits analysis, this exposes some normalization shortcoming of SCEVs:
%div = udim i32 %a, 65536
%mul = mul i32 %div, 65536
%rem = urem i32 %a, 65536
%add = add i32 %mul, %rem

Re-enable "[MachineCopyPropagation] Extend pass to do COPY source forwarding"
Issues addressed since original review:
- Moved removal of dead instructions found by
LiveIntervals::shrinkToUses() outside of loop iterating over
instructions to avoid instructions being deleted while pointed to by
iterator.
- Fixed ARMLoadStoreOptimizer bug exposed by this change in r311907.
- The pass no longer forwards COPYs to physical register uses, since
doing so can break code that implicitly relies on the physical
register number of the use.
- The pass no longer forwards COPYs to undef uses, since doing so
can break the machine verifier by creating LiveRanges that don't
end on a use (since the undef operand is not considered a use).
[MachineCopyPropagation] Extend pass to do COPY source forwarding
This change extends MachineCopyPropagation to do COPY source forwarding.
This change also extends the MachineCopyPropagation pass to be able to
be run during register allocation, after physical registers have been
assigned, but before the virtual registers have been re-written, which
allows it to remove virtual register COPY LiveIntervals that become dead
through the forwarding of all of their uses.

Prior to this patch we had a DAG combine that tried to bypass an X86ISD::ADD with -1 being added to the carry flag of some previous operation. We would then pass the carry flag directly to user.

comarison against `iv.next`. If the actual comparison is made against the `iv` current value
then the loop may be rejected, because this misinterpretation leads to incorrect evaluation
of the latch start value.
This patch teaches the IRCE to distinguish this kind of loops and perform the optimization
for them. Now we use `IndVarBase` variable which can be either next or current value of the
induction variable (previously we used `IndVarNext` which was always the value on next iteration).

AMDGPU: Use set for tracked registers
The majority of the time spent in the pass checking
for the register reads. Rather than searching all of
the defined registers for uses in each instruction,
use a set of defined registers and check the operands
of the instruction.
This process still is algorithmically not great,
but with the additional trick of skipping the analysis
for addresses with one use, this brings one slow
testcase into a reasonable range.

[XRay][tools] Fix an accounting bug in llvm-xray account
Summary:
Before this patch, llvm-xray account will assume that thread stacks will
not be empty. Unfortunately there are cases where an instrumented
function will see a call to `fork()` which will cause the child process
to not see the start of the function, but only see the end of the
function. The tooling cannot assume that threads will always have
perfect stacks, and so we change it to support this reality.

cmake: Invent add_llvm_fuzzer to set up fuzzer targets
This moves the cmake configuration for fuzzers in LLVM to a new macro,
add_llvm_fuzzer. This will make it easier to keep things consistent
while implementing llvm.org/pr34314.
I've also made a couple of minor functional changes here:
- the fuzzers now use add_llvm_executable rather than add_llvm_tool.
This means they won't create install targets and stuff like that,
because those made little sense for these fuzzers.
- I've grouped these under "Fuzzers" rather than in with "Tools" for
people who build with IDEs.
