need the soname to stay consistent for all Major.Minor.* releases

834384bf5b Split GlobalValue into GlobalValue and GlobalObject.
This allows code to statically accept a Function or a GlobalVariable, but
not an alias. This is already a cleanup by itself IMHO, but the main
reason for it is that it gives a lot more confidence that the refactoring to fix
the design of GlobalAlias is correct. That will be a followup patch.

fdae312e65 [CGP] r205941 changed the logic, so that a cast happens *before* 'Result' is
compared to 'AddrMode.BaseReg'. In the case that 'AddrMode.BaseReg' is
nullptr, 'Result' will also be nullptr, so the cast causes an assertion. We
should use dyn_cast_or_null here to check 'Result' is not null and it is an
instruction.

Bug found by Mats Petersson, and I reduced his IR to get a test case.

0e0f907356 [mips] Marked up instructions added in MIPS32r2 and tested that IAS for -mcpu=mips(2|32) does not accept them
Summary:
This required a new instruction group representing the 32-bit subset of
MIPS-3 that was available in MIPS32R2.

To limit the number of tests required, only one 32-bit and one 64-bit ISA
prior to MIPS32/MIPS64 are tested.

rdhwr has been deliberately left without an ISA annotation for now. This is
because the assembler and CodeGen disagree on when the instruction is
available. Strictly speaking, it is only available in MIPS32r2 and
MIPS64r2. However, it is emulated by a kernel trap on earlier ISA's and is
necessary for TLS so CodeGen should emit it on older ISA's too.

Depends on D3696

fc2427bcf8 [mips] Free up two values in SubtargetFeatureFlag by folding the redundant IsGP32/IsGP64 into IsGP32bit/IsGP64bit
Summary:
We are currently very close to the 32-bit limit of the current assembler
implementation. This is because there is no way to represent an instruction
that is available in, for example, Mips3 or Mips32. We have to define a
feature bit that represents this.

This patch cleans up a pair of redundant feature bits and slightly postpones the
point we will reach the limit.

5a5a0640d8 Use a logical not when inverting SetCC. This unfortunately doesn't fire on any targets so I couldn't find a test case to trigger it.
The problem occurs when a non-i1 setcc is inverted.  For example 'i8 = setcc' will get 'xor 0xff' to invert this.   This is clearly wrong when the boolean contents are ZeroOrOne.

This patch introduces getLogicalNOT and updates SetCC legalisation to use it.

73282018a1 [DAGCombiner] Split up an indexed load if only the base pointer value is live
Right now the load may not get DCE'd because of the side-effect of updating
the base pointer.

This can happen if we lower a read-modify-write of an illegal larger type
(e.g. i48) such that the modification only affects one of the subparts (the
lower i32 part but not the higher i16 part).  See the testcase.

In order to spot the dead load we need to revisit it when SimplifyDemandedBits
decided that the value of the load is masked off.  This is the
CommitTargetLoweringOpt piece.

I checked compile time with ARM64 by sending SPEC bitcode files through llc.
No measurable change.

17335ce80f Try to fix an SDAG dependence issue with sret
r208453 added support for having sret on the second parameter.  In that
change, the code for copying sret into a virtual register was hoisted
into the loop that lowers formal parameters.  This caused a "Wrong
topological sorting" assertion failure during scheduling when a
parameter is passed in memory.  This change undoes that by creating a
second loop that deals with sret.

I'm worried that this fix is incomplete.  I don't fully understand the
dependence issues.  However, with this change we produce the same DAGs
we used to produce, so if they are broken, they are just as broken as
they have always been.
