than on MipsSubtargetInfo.
This required a bit of massaging in the MC level to handle this since
MC is a) largely a collection of disparate classes with no hierarchy,
and b) there's no overarching equivalent to the TargetMachine, instead
only the subtarget via MCSubtargetInfo (which is the base class of
TargetSubtargetInfo).
We're now storing the ABI in both the TargetMachine level and in the
MC level because the AsmParser and the TargetStreamer both need to
know what ABI we have to parse assembly and emit objects. The target
streamer has a pointer to the one in the asm parser and is updated
when the asm parser is created. This is fragile as the FIXME comment
notes, but shouldn't be a problem in practice since we always
create an asm parser before attempting to emit object code via the
assembler. The TargetMachine now contains the ABI so that the DataLayout
can be constructed dependent upon ABI.
All testcases have been updated to use the -target-abi command line
flag so that we can set the ABI without using a subtarget feature.
Should be no change visible externally here.

Summary:
This puts all the options that CommandLine.cpp implements into a category so that the APIs to hide options can not hide based on the generic category instead of string matching a partial list of argument strings.
This patch is pretty simple and straight forward but it does impact the -help output of all tools using cl::opt. Specifically the options implemented in CommandLine.cpp (help, help-list, help-hidden, help-list-hidden, print-options, print-all-options, version) are all grouped together into an Option category, and these options are never hidden by the cl::HideUnrelatedOptions API.

Summary:
This patch adds support for some operations that were missing from
128-bit integer types (add/sub/mul/sdiv/udiv... etc.). With these
changes we can support the __int128_t and __uint128_t data types
from C/C++.
Depends on D7125

Extend the triple parsing to support this. Avoid running the ARM parser
multiple times because StringSwitch is not lazy.

This reverts commit r227003. Support for addition/subtraction and
various other operations for the i128 data type will be added in a
future commit based on the review D7143.

-no-exec-stack. This was due to it not deriving from the correct
asm info base class and missing the override for the exec
stack section query. Added another line to the noexec test
line to make sure this doesn't regress.

physical register that is described in a DBG_VALUE.
In the testcase the DBG_VALUE describing "p5" becomes unavailable
because the register its address is in is clobbered and we (currently)
aren't smart enough to realize that the value is rematerialized immediately
after the DBG_VALUE and/or is actually a stack slot.

It appears we have different behavior with and without -mcpu=pwr8 even
with ppc64le defaulting to POWER8. The failure appears as follows:

Test by Nemanja Ivanovic.
Since ppc64le implies POWER8 as a minimum, it makes sense that the
same features are included. Since the pwr8 processor model will likely
be getting new features until the implementation is complete, I
created a new list to add these updates to. This will include them in
both pwr8 and ppc64le.
Furthermore, it seems that it would make sense to compose the feature
lists for other processor models (pwr3 and up). Per discussion in the
review, I will make this change in a subsequent patch.
In order to test the changes, I've added an additional run step to
test cases that specify -march=ppc64le -mcpu=pwr8 to omit the -mcpu
option. Since the feature lists are the same, the behaviour should be
unchanged.

MIPS64 ELF file has a very specific relocation record format. Each
record might specify up to three relocation operations. So the `r_info`
field in fact consists of three relocation type sub-fields and optional
code of "special" symbols.
http://techpubs.sgi.com/library/manuals/4000/007-4658-001/pdf/007-4658-001.pdf
page 40
The patch implements support of the MIPS64 relocation record format in
yaml2obj/obj2yaml tools by introducing new optional Relocation fields:
Type2, Type3, and SpecSym. These fields are recognized only if the
object/YAML file relates to the MIPS64 target.

that library consumers access the instcombine pass directly, they also
(transitively) access the worklist. Also, it would need to be used
directly in order to have a useful utility if we ever want that.
This should fix some warnings since I moved this code. Sorry for the
trouble.

If two coverage segments cover the same area we need to combine them,
as per r218432. OTOH, just because they start at the same place
doesn't mean they cover the same area. This fixes the check to be more
exact about this.
This is pretty hard to test right now. The frontend doesn't currently
emit regions that start at the same place but don't overlap, but some
upcoming work changes this.
