Summary:
These operands had the same purpose, however the MipsMemSimm9GPRAsmOperand
operand was only for micromips32r6 and the MipsMemSimm9AsmOperand did not
have a ParserMatchClass.

The iterator pointing to an element of a dense map was used after
the element from was removed from the map what isn't guaranteed to be
valid at that time.

GetElementPointers must have the first argument's type compared
for structural equivalence. Previously the code erroneously compared the
pointer's type, but this code was dead because all pointer types (of the
same address space) are the same. The pointee must be compared instead
(using the type stored in the GEP, not from the pointer type which will
be erased anyway).

Turning (op x (mul y k)) into (op x (lsl (mul y k>>n) n)) is beneficial when
we can do the lsl as a shifted operand and the resulting multiply constant is
simpler to generate.
Do this by doing the transformation when trying to select a shifted operand,
as that ensures that it actually turns out better (the alternative would be to
do it in PreprocessISelDAG, but we don't know for sure there if extracting the
shift would allow a shifted operand to be used).

This test passes locally but was disabled due to pexpect issues on the
FreeBSD buildbot. That buildbot has been retired as it was overloaded,
and we will investigate again if this fails once a new buildbot is in
place. Noted by John Wolfe.

RegisterContextPOSIX.h is poorly named and contains only the declaration
of POSIXBreakpointProtocol, which is used for in-process live kernel
debugging. It is now relevant only to FreeBSD.
In source/Plugins/Process/Utility/RegisterContext*.h (after assorted
rework and refactoring) it only served the purpose of #including other
necessary headers as a side-effect. Remove it from them and just include
the required headers directly.

The MipsTargetELFStreamer can receive ABI info from many sources. For example,
from the MipsAsmParser instance. Lifetime of the MipsAsmParser can be shorter
than MipsTargetELFStreamer's lifetime. In that case we get a dangling pointer
to MipsABIInfo.

At some point we build loop trip counts using this method. It was replaced by
a simpler trick that works only for affine (e.g., not modulo) constraints and
relies on the removal of unbounded parts. In order to allow modulo constrains
again we go back to the former, more accurate method.

Summary:
Realtime signals generally do not represent an error condition in an application but are more
like a regular means of IPC. As such, we shouldn't interrupt an application whenever it recieves
one. If any application will use these signals, it will probably use them a lot, rendering it's
debugging tiresome if we stopped at every signal. Furthermore, these signals are likely to be used
in a low level library, and the programmer may not even be aware of their presence.
For these reasons, I am switching the default disposition of realtime signals on all supported
platforms (i.e. Linux and Freebsd) to no-stop, no-notify. Any user still wishing to receive these
signals can always change the default to suit his needs.

DeletionCallbackHandle holds GAR in its creation. It assumes;
- It is registered as CallbackVH. It should not be moved in its life.
- Its parent, GAR, may be moved.
To move list<DeletionCallbackHandle> GlobalsAAResult::Handles,
GAR must be updated with the destination in GlobalsAAResult(&&).

of a method and into a re-usable static helper. We can potentially use
this function from the implementation of a new pass manager oriented
version of the pass. Also add some better documentation of exactly what
the semantic model of this routine is (it isn't trivial) and use a more
modern naming convention for it.

KNL does not have VXORPS, VORPS for 512-bit values.
I use integer VPXOR, VPOR that actually do the same.
X86ISD::FXOR/FOR are generated as a result of FSUB combining.

static function rather than a method. It just needed access to
TargetLibraryInfo, and this way it can be easily reused between the
current FunctionAttrs implementation and any port for the new pass
manager.
