edbc0df974 [InstCombine] Rephrase fix to SimplifyWithOpReplaced
I don't have the IR which is causing the build bot breakage but I can
postulate as to why they are timing out:
1. SimplifyWithOpReplaced was stripping flags from the simplified value.
2. visitSelectInstWithICmp was overriding SimplifyWithOpReplaced because
   it's simplification wasn't correct.
3. InstCombine would revisit the add instruction and note that it can
   rederive the flags.
4. By modifying the value, we chose to revisit instructions which reuse
   the value.  One of the instructions is the original select, causing
   LLVM to never reach fixpoint.

Instead, strip the flags only when we are sure we are going to perform
the simplification.

2a89c94df6 Revert "[InstCombine] Don't miscompile safe increment idiom"
This is breaking a lot of build bots and is causing very long-running
compiles (infinite loops)?

Likely, we shouldn't return nullptr?

0a64b6de98 InstrProf: Fix reading of consecutive 32 bit coverage maps
When we generate coverage data, we explicitly set each coverage map's
alignment to 8 (See InstrProfiling::lowerCoverageData), but when we
read the coverage data, we assume consecutive maps are exactly
adjacent. When we're dealing with 32 bit, maps can end on a 4 byte
boundary, causing us to think the padding is part of the next record.

Fix this by adjusting the buffer to an appropriately aligned address
between records.

This is pretty awkward to test, as it requires a binary with multiple
coverage maps to hit, so we'd need to check in multiple source files
and a binary blob as inputs.

b0b8cde9d4 [InstCombine] Don't miscompile safe increment idiom
We cleverly handle cases where computation done in one argument of a select
instruction is suitable for the other operand, thus obviating the need
of the select and the comparison.  However, the other operand cannot
have flags.

This fixes PR23757.

bb3883dfba Statepoint: Fix handling of Far Immediate calls
gc.statepoint intrinsics with a far immediate call target 
were lowered incorrectly as pc-rel32 calls.

This change fixes the problem, and generates an indirect call 
via a scratch register.

For example: 

Intrinsic:
  %safepoint_token = call i32 (i64, i32, void ()*, i32, i32, ...) @llvm.experimental.gc.statepoint.p0f_isVoidf(i64 0, i32 0, void ()* inttoptr (i64 140727162896504 to void ()*), i32 0, i32 0, i32 0, i32 0)

Old Incorrect Lowering:
  callq 140727162896504

New Correct Lowering:
  movabsq $140727162896504, %rax 
  callq *%rax

In lowerCallFromStatepoint(), the callee-target was modified and 
represented as a "TargetConstant" node, rather than a "Constant" node.
Undoing this modification enabled LowerCall() to generate the 
correct CALL instruction.

c9f2b5d535 [SDAG switch lowering] Fix switch case -> or merging for 0 and INT_MIN
The big/small ordering here is based on signed values so SmallValue will
be INT_MIN and BigValue 0. This shouldn't be a problem but the code
assumed that BigValue always had more bits set than SmallValue.

We used to just miss the transformation, but a recent refactoring of
mine turned this into an assertion failure.

6782fc61ca Simplify ARMTargetParser::getArchSynonym
Summary:
1) The only caller, ARMTargetParser::parseArch, uses the results for an "endswith" test; so, including the "arm" prefix into the result is unnecessary.
2) Most ARMTargetParser::parseArch callers pass it the output from ARMTargetParser::getCanonicalArchName; so, make this behaviour the default. Then, including the "arm" prefix into the cases is unnecessary.

Apparently this functionality isn't used in-tree (or I would go & make

make them more self documenting now that clone doesn't return a raw

ideal.

a8dc0ee520 Erase constant dbgloc on reuse in PHI node
Basic block selection involves checking successor BBs for PHI nodes
that depend on the current BB.  In case such BBs are found, the value
being selected is a constant and such constant already exists in
current BB, it's value is reused.

This might lead to wrong locations in some situations, especially if
same constant value ends up being materialized twice in two different
ways, which discards that sharing and leaves us with wrong debug
location in the successor BB.

In code this involves the following sequence of calls:

 SelectionDAGBuilder::HandlePHINodesInSuccessorBlocks ->
 SelectionDAGBuilder::CopyValueToVirtualRegister ->
 SelectionDAGBuilder::getNonRegisterValue

Originally committed in r237975, GCC 4.7 gave a compilation error
regarding "looser throw specification" though it seemed to be pointing
to a virtual defaulted dtor in a base class and an override defaulted
dtor in a derived class - so I'm not quite sure why/how they could end
up with different throw specifications. To simplify and reduce the risk
of this, I've just removed the pointless override in the derived class,
the base class's should be sufficient. *fingers crossed*

NVPTXFavorNonGenericAddrSpaces, allows the NVPTX backend to emit ld.global.*

fbfbe05819 [CMake] Fixing the check for Ninja
Enabling Ninja Job Pools needs to be dependent on the CMAKE_MAKE_PROGRAM not the CMAKE_GENERATOR. There are generators (like "Sublime Text 2 - Ninja") that also generate ninja build files. Basing of the CMAKE_MAKE_PROGRAM is the best future-proof way to handle this.

d7eb7d7fb1 [Object, MachO] Cache parsed MachO header in MachOObjectFile. NFC.
Summary:
Avoid parsing object file each time MachOObjectFile::getHeader() is
called. Instead, cache the header in MachOObjectFile constructor, where
it's parsed anyway. In future, we must avoid constructing the object
at all if the header can't be parsed.

Test Plan: regression test suite.

ac73683b10 [bpf] add big- and host- endian support
Summary:
-march=bpf    -> host endian
-march=bpf_le -> little endian
-match=bpf_be -> big endian

Test Plan:
v1 was tested by IBM s390 guys and appears to be working there.
It bit rots too fast here.
