ea82d0311b [arm64] Use BTI instructions for forward CFI
Generate a BTI instruction at each target of an indirect branch
(BR/BLR). An indirect branch that doesn't jump to a BTI instruction
will generate an exception on a BTI-enabled core. On cores that do
not support the BTI extension, the BTI instruction is a NOP.

Targets of indirect branch instructions include, among other things,
function entrypoints, exception handlers and jump tables. Lazy deopt
exits can potentially be reached through an indirect branch when an
exception is thrown, so they also get an additional BTI instruction.

8199a7ac23 [ppc64][ppc] Split up ARCH_PPC and ARCH_PPC64
After support for ARCH_PPC was dropped, it became a subset of
ARCH_PPC64. If you compile for ppc64, then you set the ARCH_PPC64
define which also sets the ARCH_PPC define.
To be able to again support ppc (32 bit) those defines should be
split up again.

This commit only splits up the defines but does not introduce a
working ARCH_PPC variant.

this CL gives A's ownership to B.

Before, we used to say that B didn't have ownership of A due to A having
two uses.

This brings it in line with OwnedBy with two owners check:

2cd24ebab9 [compiler] Consider pushed arguments in stack check offset
Function calls can push arguments onto the stack. The consumed stack
slots are not considered by the function-entry stack check, since
initial frame setup only reserves space for local slots, not call
arguments. This CL adds such logic by tracking the maximum pushed
argument count during instruction selection, and adding these slots to
the (existing) stack check offset logic in code generation.

25f242ad76 Remove --perf-prof flag on non-linux
The fuzzers picked up this flag, and are now complaining that they run
into UNREACHABLE/FATAL too often because the {PerfJitLogger} is not
implemented on non-linux platforms.
This CL removes the flag if it's not supported, so users get a warning
about the unknown flag, but otherwise it's ignored. This should unblock
the fuzzers, and slightly reduces binary size on non-linux.

dde3166beb [wasm] Remove one {NewNativeModule} method
This makes the {code_size_estimate} computation explicit in the caller,
and removes one of the two {NewNativeModule} constructors. It turns out
that the calculation is totally off in the streaming calculation phase,
since no function bodies have been parsed yet. So all
{WasmFunction::code} fields are still empty, and we compute an estimate
that is way too low.
This CL prepares the actual fix for that (by computing a better estimate
at specific call sites).

Introduce new operator LoadTransform that holds a LoadTransformInfo param,
which describes the kind of load (normal, unaligned, protected), and a
transformation (splat or extend, signed or unsigned).

We have a new method that a full decoder needs to implement, LoadTransform,
which resuses the existing LoadType we have, but also takes a LoadTransform,
to distinguish between splats and extends at the decoder level.

This implements 4 out of the 10 suggested load splat/extend operations
(to keep the cl smaller), and is also missing interpreter support (will
be added in the future).

This makes TSAN happy in addition to:

Previously I presumed that the context read from a frame in the profiler was
a valid context. Turns out that on non-intel we're not guaranteed that the
frame is properly set up. In the case we looked at, the profiler took a
sample right before writing the frame marker indicating a builtin frame,
causing the "context" pointer from that frame to be a bytecode array. Since
we'll read random garbage on the stack as a possible context pointer, I made
the code reading the native context from it a little more defensive.

8d10768442 Avoid defining class name Label as type alias in cctest because it is used by V8
It is not recommended to define type alias in C++ header file. cctest defines
type alias `using Label=CodeAssemblerLabel` in anonymous namespace under
namespace `v8::internal::compiler` in test-code-assembler.cc. This is fine
because this type alias is expected to take effect only in this .cc file. But in
jumbo build, multiple source files are combined as a single one, and the
previous `Label` type alias could shadow definition of `Label` from other header
file (for example, v8/src/codegen/label.h which is included by another .cc file)
This is totally unexpected and triggers bad class layout and accessing in the
latter .cc file for the places where `Label` is referenced.

This change fixes cctest from Windows ARM64 jumbo build, but it applies to
other architectures too.

51d1573b2a [turbofan] Simplify handling of calls with saved registers.
This removes the explicit {kCallWithCallerSavedRegisters} opcode which
is just a regular call node with special handling for saving/restoring
caller saved registers before/after the call. This is now handled via
the {CallDescriptor::kCallerSavedRegisters} flag.
