-Wno-suggest-override getting passed to the Windows Resource Compiler
because it was added with add_definitions in the CMake file.

We can just use the definition from config.h. This means we need to move

This was structured in a way that implied every split argument is in
memory, or in registers. It is possible to pass an original argument
partially in registers, and partially in memory. Transpose the logic
here to only consider a single piece at a time. Every individual
CCValAssign should be treated independently, and any merge to original
value needs to be handled later.
This is in preparation for merging some preprocessing hacks in the
AMDGPU calling convention lowering into the generic code.
I'm also not sure what the correct behavior for memlocs where the
promoted size is larger than the original value. I've opted to clamp
the memory access size to not exceed the value register to avoid the
explicit trunc/extend/vector widen/vector extract instruction. This
happens for AMDGPU for i8 arguments that end up stack passed, which
are promoted to i16 (I think this is a preexisting DAG bug though, and
they should not really be promoted when in memory).
For now, xdrrec_create is only intercepted Linux as its signature
is different on Solaris.
The method of intercepting xdrrec_create isn't super ideal but I
couldn't think of a way around it: Using an AddrHashMap combined
with wrapping the userdata field.
We can't just allocate a handle on the heap in xdrrec_create and leave
it at that, since there'd be no way to free it later. This is because it
doesn't seem to be possible to access handle from the XDR struct, which
is the only argument to xdr_destroy.
On the other hand, the callbacks don't have a way to get at the
x_private field of XDR, which is what I chose for the HashMap key. So we
need to wrap the handle parameter of the callbacks. But we can't just
pass x_private as handle (as it hasn't been set yet). We can't put the
wrapper struct into the HashMap and pass its pointer as handle, as the
key we need (x_private again) hasn't been set yet.
So I allocate the wrapper struct on the heap, pass its pointer as
handle, and put it into the HashMap so xdr_destroy can find it later and
destroy it.

A previous patch added -Wsuggest-override using a simple add_flag_if_supported(). This causes lots of warnings in LLVM when building with older GCC versions (< 9.2) which suggest adding override to functions that are only marked final. The current flags in both GCC >=9.2 and Clang accept plain final as equivalent to override final.
This patch adds logic to detect versions of -Wsuggest-override that warn on void foo() final and disables them to avoid warning spam in builds using older GCC's. This has the added minor benefit of getting rid of the useless C_SUPPORTS_SUGGEST_OVERRIDE_FLAG CMake cache variable which was set by add_flag_if_supported().

These calls are neither intercepted by compiler-rt nor is libatomic.a
naturally instrumented.
This patch uses the existing libcall mechanism to detect a call
to atomic_load or atomic_store, and instruments them much like
the preexisting instrumentation for atomics.
Calls to _load are modified to have at least Acquire ordering, and
calls to _store at least Release ordering. Because this needs to be
converted at runtime, msan injects a LUT (implemented as a vector
with extractelement).

Summary:
This patch implements semantics for the 'arm_sve_vector_bits' type
attribute, defined by the Arm C Language Extensions (ACLE) for SVE [1].
The purpose of this attribute is to define fixed-length (VLST) versions
of existing sizeless types (VLAT).
Implemented in this patch is the the behaviour described in section 3.7.3.2
and minimal parts of sections 3.7.3.3 and 3.7.3.4, this includes:
* Defining VLST globals, structs, unions, and local variables
* Implicit casting between VLAT <=> VLST.
* Diagnosis of ill-formed conditional expressions of the form:
C ? E1 : E2
where E1 is a VLAT type and E2 is a VLST, or vice-versa. This
avoids any ambiguity about the nature of the result type (i.e is
it sized or sizeless).
* For vectors:
* sizeof(VLST) == N/8
* alignof(VLST) == 16
* For predicates:
* sizeof(VLST) == N/64
* alignof(VLST) == 2
VLSTs have the same representation as VLATs in the AST but are wrapped
with a TypeAttribute. Scalable types are currently emitted in the IR for
uses such as globals and structs which don't support these types, this
is addressed in the next patch with codegen, where VLSTs are lowered to
sized arrays for globals, structs / unions and arrays.
Not implemented in this patch is the behaviour guarded by the feature
macros:
* __ARM_FEATURE_SVE_VECTOR_OPERATORS
* __ARM_FEATURE_SVE_PREDICATE_OPERATORS
As such, the GNU __attribute__((vector_size)) extension is not available
and operators such as binary '+' are not supported for VLSTs. Support
for this is intended to be addressed by later patches.

This patch has no effect for C and C++. In more dynamic languages,
such as Objective-C and Swift GetByteSize() needs to call into the
language runtime, so it's important to pass one in where possible. My
primary motivation for this is some work I'm doing on the Swift
branch, however, it looks like we are also seeing warnings in
Objective-C that this may resolve. Everything in the SymbolFile
hierarchy still passes in nullptrs, because we don't have an execution
context in SymbolFile, since SymbolFile transcends processes.

16-bit literals are encoded as 32-bit values. If high 16-bits of the value is 0xFFFF, the decoded instruction cannot be reassembled.
For example, the following code
0xff,0x04,0x04,0x52,0xcd,0xab,0xff,0xff
was decoded as
v_mul_lo_u16_e32 v2, 0xffffabcd, v2
However this literal is actually a 64-bit constant 0x00000000ffffabcd which violates requirements described in the documentation - the truncation is not safe.
This change corrects decoding to make reassembly possible.

With a relocation to say that if we don't need to go through the GOT we can let

For a long time, the InstCombine pass handled target specific
intrinsics. Having target specific code in general passes was noted as
an area for improvement for a long time.
D81728 moves most target specific code out of the InstCombine pass.
Applying the target specific combinations in an extra pass would
probably result in inferior optimizations compared to the current
fixed-point iteration, therefore the InstCombine pass resorts to newly
introduced functions in the TargetTransformInfo when it encounters
unknown intrinsics.
The patch should not have any effect on generated code (under the
assumption that code never uses intrinsics from a foreign target).
This introduces three new functions:
TargetTransformInfo::instCombineIntrinsic
TargetTransformInfo::simplifyDemandedUseBitsIntrinsic
TargetTransformInfo::simplifyDemandedVectorEltsIntrinsic
A few target specific parts are left in the InstCombine folder, where
it makes sense to share code. The largest left-over part in
InstCombineCalls.cpp is the code shared between arm and aarch64.
This allows to move about 3000 lines out from InstCombine to the targets.
