MIR SRADI uses instruction template XSForm_1rc which declares Defs = [CARRY]. But MIR SRADI_32 uses instruction template XSForm_1, and it doesn't declare such implicit definition. With patch D33720 it causes wrong code generation for perl.
This patch adds the implicit definition.

This patch makes LSR generate better code for SystemZ in the cases of memory
intrinsics, Load->Store pairs or comparison of immediate with memory.
In order to achieve this, the following common code changes were made:
* New TTI hook: LSRWithInstrQueries(), which defaults to false. Controls if
LSR should do instruction-based addressing evaluations by calling
isLegalAddressingMode() with the Instruction pointers.
* In LoopStrengthReduce: handle address operands of memset, memmove and memcpy
as address uses, and call isFoldableMemAccessOffset() for any LSRUse::Address,
not just loads or stores.
SystemZ changes:
* isLSRCostLess() implemented with Insns first, and without ImmCost.
* New function supportedAddressingMode() that is a helper for TTI methods
looking at Instructions passed via pointers.

Currently we only support (i32 bitcast(v32i1)) using the AVX2 VPMOVMSKB ymm instruction.
This patch adds support for splitting pre-AVX2 targets into 2 x (V)PMOVMSKB xmm instructions and merging the integer results.
In future we could probably generalize this to handle more cases.

It revealed a bug in the Localizer pass which has now been fixed.

The patch adds support of i128 params lowering. The changes are quite trivial to
support i128 as a "special case" of integer type. With this patch, we lower i128
params the same way as aggregates of size 16 bytes: .param .b8 _ [16].
Currently, NVPTX can't deal with the 128 bit integers:
* in some cases because of failed assertions like
ValVTs.size() == OutVals.size() && "Bad return value decomposition"
* in other cases emitting PTX with .i128 or .u128 types (which are not valid [1])

Move the _RTN to the end of the name. It reads
better if the other addressing mode components
line up with the non-RTN version. It is also
more convenient to define saddr variants of
FLAT atomics to have the RTN last, and it is
good to have a consistent naming scheme.

On AMDGPU SGPR spills are really spilled to another register.
The spiller creates the spills to new frame index objects,
which is used as a placeholder.
This will eventually be replaced with a reference to a position
in a VGPR to write to and the frame index deleted. It is
most likely not a real stack location that can be shared
with another stack object.
This is a problem when StackSlotColoring decides it should
combine a frame index used for a normal VGPR spill with
a real stack location and a frame index used for an SGPR.
Add an ID field so that StackSlotColoring has a way
of knowing the different frame index types are
incompatible.

Summary:
Also enable no-fsmuld for sparcv7 (which doesn't have the
instruction).
The previous code which used a post-processing pass to do this was
unnecessary; disabling the instruction is entirely sufficient.

Introduced FSELECT node necesary when lowering ISD::SELECT
which has i32, f64, f64 as its operands.
SEL_D instruction required that its output and first operand
of a SELECT node, which it used, have matching types.
MTC1_D64 node introduced to aid FSELECT lowering.

The soffset field needs to be be set to 0x7f to disable it,
not 0. 0 is interpreted as an SGPR offset.
This should be enough to get basic usage of the global instructions
working. Technically it is possible to use an SGPR_32 offset,
but I'm not sure if it's correct with 64-bit pointers, but
that is not handled now. This should also be cleaned up
to be more similar to how different MUBUF modes are handled,
and to have InstrMappings between the different types.

This generalizes an existing fix from ELF to MachO and COFF.
Test that an ADRP to a local symbol whose offset is known at assembly
time still produces relocations, both for MachO and COFF. Test that
an ADRP without a @page modifier on MachO fails (previously it
didn't).

This patch cleans up and fixes issues in the M-Class system register handling:
1. It defines the system registers and the encoding (SYSm values) in one place:
a new ARMSystemRegister.td using SearchableTable, thereby removing the
hand-coded values which existed in multiple places.
2. Some system registers e.g. BASEPRI_MAX_NS which do not exist were being allowed!

Summary:
This patch adds the following
1. Adds a skeleton scheduler model for AMD Znver1.
2. Introduces the znver1 execution units and pipes.
3. Caters the instructions based on the generic scheduler classes.
4. Further additions to the scheduler model with instruction itineraries will be carried out incrementally based on
a. Instructions types
b. Registers used
5. Since itineraries are not added based on instructions, throughput information are bound to change when incremental changes are added.
6. Scheduler testcases are modified accordingly to suit the new model.
Patch by Ganesh Gopalasubramanian. With minor formatting tweaks from me.
