gn build: Add NVPTX target
The NVPTX target is a bit unusual in that it's the only target without a
disassembler, and one of three targets without an asm parser (and the
first one of those three in the gn build). NVPTX doesn't have those
because it's not a binary format.
The CMake build checks for the existence of
{AsmParser,Disassembler}/CMakeLists.txt when setting
LLVM_ENUM_ASM_PARSERS / LLVM_ENUM_DISASSEBLERS
(http://llvm-cs.pcc.me.uk/CMakeLists.txt#744). The GN build doesn't want
to hit the disk for things like this, so instead I'm adding explicit
`targets_with_asm_parsers` and `targets_with_disassemblers` lists. Since
both are needed rarely, they are defined in their own gni files.

I recently discovered a bug on the x86 platform: The fp80 type was not handled well by x86 for constrained floating point nodes, as their regular counterparts are replaced by extending loads and truncating stores during the preprocess phase. Normally, platforms don't have this issue, as they don't typically attempt to perform such legalizations during instruction selection preprocessing. Before this change, strict_fp nodes survived until they were mutated to normal nodes, which happened shortly after preprocessing on other platforms. This modification lowers these nodes at the same phase while properly utilizing the chain.5

GlobalISel: Avoid producing Illegal copies in RegBankSelect
Avoid producing illegal register bank copies for reg_sequence and
phi. The default implementation assumes it is possible to pick any
operand's bank and use that for the result, introducing a copy for
operands with a different bank. This does not check for illegal
copies. It is not legal to introduce a VGPR->SGPR copy, so any VGPR
operand requires the result to be a VGPR.
The changes in getInstrMappingImpl aren't strictly necessary, since
AMDGPU now just bypasses this for reg_sequence/phi. This could be
replaced with an assert in case other targets run into this. It is
currently responsible for producing the error for unsatisfiable
copies, but this will be better served with a verifier check.
For phis, for now assume any undetermined operands must be
VGPRs. Eventually, this needs to be able to defer mapping these
operations. This also does not yet have a way to check for whether the
block is in a divergent region.

[llvm-readobj] - Do not fail to dump the object which has wrong type of .shstrtab.
Imagine we have object that has .shstrtab with type != SHT_STRTAB.
In this case, we fail to dump the object, though GNU readelf dumps it without
any issues and warnings.
This patch fixes that. It adds a code to ELFDumper.cpp which is based on the implementation of getSectionName from the ELF.h:
https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Object/ELF.h#L608
https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Object/ELF.h#L431
https://github.com/llvm-mirror/llvm/blob/master/include/llvm/Object/ELF.h#L539
The difference is that all non critical errors are ommitted what allows us to
improve the dumping on a tool side. Also, this opens a road for a follow-up that
should allow us to dump the section headers, but drop the section names in case if .shstrtab is completely absent and/or broken.

[ARM] MVE VPT Block Pass
Initial commit of a new pass to create vector predication blocks, called VPT
blocks, that are supported by the Armv8.1-M MVE architecture.
This is a first naive implementation. I.e., for 2 consecutive predicated
instructions I1 and I2, for example, it will generate 2 VPT blocks:
VPST
I1
VPST
I2
A more optimal implementation would obviously put instructions in the same VPT
block when they are predicated on the same condition and when it is allowed to
do this:
VPTT
I1
I2
We will address this optimisation with follow up patches when the groundwork is
in. Creating VPT Blocks is very similar to IT Blocks, which is the reason I
added this to Thumb2ITBlocks.cpp. This allows reuse of the def use analysis
that we need for the more optimal implementation.
VPT blocks cannot be nested in IT blocks, and vice versa, and so these 2 passes
cannot interact with each other. Instructions allowed in VPT blocks must
be MVE instructions that are marked as VPT compatible.

When we build NodeOrder in Scheduler, we ignore these boundary nodes.
However, when we check Succs in checkValidNodeOrder, we did not skip

* Spelling out that instructions depending on poison return poison.
* Spelling out how we go from a poison value to immediate undefined

[lit] Disable test on darwin when building shared libs.
Summary:
This test fails to link shared libraries because tries to run
a copied version of clang-check to see if the mock version of libcxx
in the same directory can be loaded dynamically. Since the test is
specifically designed not to look in the default just-built lib
directory, it must be disabled when building with
BUILD_SHARED_LIBS=ON.
Currently only disabling it on Darwin and basing it on the
enable_shared flag.

[LFTR] Rename variable to minimize confusion [NFC]
As pointed out by Nikita in D62625, BackedgeTakenCount is generally used to refer to the backedge taken count of the loop. A conditional backedge taken count - one which only applies if a particular exit is taken - is called a ExitCount in SCEV code, so be consistent here.
