[PPC64] Fix PR20071 (fctiduz generated for targets lacking that instruction)
PR20071 identifies a problem in PowerPC's fast-isel implementation for
floating-point conversion to integer. The fctiduz instruction was added in
Power ISA 2.06 (i.e., Power7 and later). However, this instruction is being
generated regardless of which 64-bit PowerPC target is selected.
The intent is for fast-isel to punt to DAG selection when this instruction is
not available. This patch implements that change. For testing purposes, the
existing fast-isel-conversion.ll test adds a RUN line for -mcpu=970 and tests
for the expected code generation. Additionally, the existing test
fast-isel-conversion-p5.ll was found to be incorrectly expecting the
unavailable instruction to be generated. I've removed these test variants
since we have adequate coverage in fast-isel-conversion.ll.

Summary:
This new debug emission kind supports emitting line location
information in all instructions, but stops code generation
from emitting debug info to the final output.
This mode is useful when the backend wants to track source
locations during code generation, but it does not want to
produce debug info. This is currently used by optimization
remarks (-pass-remarks, -pass-remarks-missed and
-pass-remarks-analysis).
To prevent debug info emission, DIBuilder never inserts the
annotation 'llvm.dbg.cu' when LocTrackingOnly is enabled.

As of r211495, the only remaining users of getMinCallFrameSize are in

good thing, since the details of the parameter save area are ABI specific.
With the new ELFv2 ABI in particular, the rules defining the size of the
save area will become significantly more complex, so it wouldn't make
sense to implement those outside ABI code that has all required
information.
In preparation, this patch eliminates the getMinCallFrameSize (and
associated getMinCallArgumentsSize) routines, and inlines them into all

[PowerPC] Allow stack frames without parameter save area
The PPCFrameLowering::determineFrameLayout routine currently ensures
that every function that allocates a stack frame provides space for the
parameter save area (via PPCFrameLowering::getMinCallFrameSize).
This is actually not necessary. There may be functions that never call
another routine but still allocate a frame; those do not require the
parameter save area. In the future, with the ELFv2 ABI, even some
routines that do call other functions do not need to allocate the
parameter save area.
While it is not a bug to allocate the parameter area when it is not
needed, it is better to avoid it to save stack space.
Note that when any particular function call requires the parameter save
area, this space will already have been included by ABI code in the size
the CALLSEQ_START insn is annotated with, and therefore included in the
size returned by MFI->getMaxCallFrameSize().
This means that determineFrameLayout simply does not need to care about
the parameter save area. (It still needs to ensure that every frame
provides the linkage area.) This is implemented by this patch.
Note that this exposed a bug in the new fast-isel code where the parameter
area was *not* included in the CALLSEQ_START size; this is also fixed.
A couple of test cases needed to be adapted for the new (smaller) stack
frame size those tests now see.

[PowerPC] Refactor setMinReservedArea and CalculateParameterAndLinkageAreaSize
The PPCISelLowering.cpp routines PPCTargetLowering::setMinReservedArea and
CalculateParameterAndLinkageAreaSize are currently used as subroutines
from both 64-bit SVR4 and Darwin ABI code.
However, the two ABIs are already quite different w.r.t. AltiVec
conventions, and they will become more different when the ELFv2 ABI is
supported. Also, in general it seems better to disentangle ABI support
routines for different ABIs to avoid accidentally affecting one ABI when
intending to change only the other.
(Actually, the current code strictly speaking already contains a bug:
these routines call PPCFrameLowering::getMinCallFrameSize and
PPCFrameLowering::getLinkageSize with the IsDarwin parameter set to
"true" even on 64-bit SVR4. This bug currently has no adverse effect
since those routines always return the same for 64-bit SVR4 and 64-bit
Darwin, but it still seems wrong ... I'll fix this in a follow-up
commit shortly.)
To remove this code sharing, I'm simply inlining both routines into all
call sites (there are just two each, one for 64-bit SVR4 and one for
Darwin), and simplifying due to constant parameters where possible.
A small piece of code that *does* make sense to share is refactored into
the new routine EnsureStackAlignment, now also called from 32-bit SVR4
ABI code.

[PowerPC] Fix on-stack AltiVec arguments with 64-bit SVR4
Current 64-bit SVR4 code seems to have some remnants of Darwin code
in AltiVec argument handing. This had the effect that AltiVec arguments
(or subsequent arguments) were not correctly placed in the parameter area
in some cases.
The correct behaviour with the 64-bit SVR4 ABI is:
- All AltiVec arguments take up space in the parameter area, just like
any other arguments, whether vararg or not.
- They are always 16-byte aligned, skipping a parameter area doubleword
(and the associated GPR, if any), if necessary.
This patch implements the correct behaviour and adds a test case.

MC: adjust text section flags for WoA
Correct the section flags for code built for Windows on ARM with
`-ffunction-sections`. Windows on ARM uses solely Thumb-2 instructions, and
indicates that the function is thumb by placing it in a text section that has
IMAGE_SCN_MEM_16BIT flag set.
When we encounter a .section directive, a new section is constructed. This may
be a text segment. In order to identify that we need the additional flag,
expose the target triple through the ObjectFileInfo as this information is lost
otherwise.
Since any modern ARM targeting environment on Windows would be Thumb-2 (Windows
ARM NT or Windows Embedded Compact), introducing a new flag to indicate the
section attribute seems to be a bit overkill. Simply depend on the target
triple. Since there is one location that this information is currently needed,
creating a target specific assembly parser and delegating the parsing of section
switches also feels a bit heavy handed. If it turns out that this information
ends up changing additional behaviour, then it may be worth considering that
alternative.

R600: Implement custom SDIVREM.
Instead of separate SDIV/SREM. SDIV used UDIV which in turn used UDIVREM anyway.
SREM used SDIV(UDIV->UDIVREM)+MUL+SUB, using UDIVREM directly is more efficient.
v2: Don't use all caps names
