This CL disables RX (read and execute) permissions for Code memory
when in jitless mode. All memory that was previously allocated RX
is now read-only.

The test allocates a code object of maximum size. This was recently
increased to 1GB. This makes the test run OOM on some native arm and
mips devices.

Instead of actually allocating an objects just test the corner cases
around the page boundary by casting addresses.

The test creates a new spaces without hooking it up into Heap, which

The tests were not flushing the i-cache before calling the generated
code. Use Factory::NewCode to make sure that the i-cache is flushed
instead.

Otherwise bots with a low number of cores will hang trying to schedule
a mere 4 tasks.
This change allowing scheduling of an arbitrary number of test tasks,
the count was also augmented to better stress test the system.

- Implement exchangeable timer clock for RuntimeCallStats for testing
- Rewrite RuntimeCAllStatsTest to overwrite the default RCS timer
This gets rid of the previous flakiness for these tests due to using
the real platform timer.

The reason:
The CL #40862 (https://codereview.chromium.org/2433093002 ) caused 2 test cases failed for X87.
Because Both 2 test cases (MoveOptimizerTest.RemovesRedundantExplicit and RegisterAllocatorTest.CanAllocateFPRegisters)
needs 2 allocatable Float/Double registers.
But there's only 1 allocatable Float/Double register in x87 turbofan compiler, i.e.: register index 0.
This CL disables MoveOptimizerTest.RemovesRedundantExplicit and RegisterAllocatorTest.CanAllocateFPRegisters test cases for x87.

With this change, WebAssembly.Memory objects have backing stores allocated as an
8GB region where everything beyond the size of the Wasm heap is inaccessible.
GrowMemory is now implemented by changing the protection on the guard regions to
make the new portions of the heap accessible.
Guard pages are not enabled by default, but this change adds a flag and a test
variant to make sure we get test coverage on them.

The reason:
same as the CL #37371 (Issue 2111493002: X87: disable some sin/cos/expm1/tan test cases for x87.), please
refer https://codereview.chromium.org/2111493002 for more details.
For Acosh/ASinh test cases, the expected values are pre-defined double precision values, the results
generated by C++ function are extended double precision as the extended double precision is default for x87
Gcc compiler and std lib on linux platform. The comparison of different precisons caused some of those test
cases failed.
This CL disables Acosh/ASinh test cases for x87.

The reason:
All RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan/Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases
use the C++ function to generate the expected value or result. So for x87, all those expected value or result are
extended double precision as the extended double precision is default for x87 Gcc compiler and std lib on linux platform.
The issue is:
For RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan test cases, the expected values generated by C++ function
are extended double precision, the results generated by X87 jitted code are double precision according to the ECMA standard.
The comparison of different precisons caused some of those test cases failed.
For Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases, the expected values are pre-defined double precision values, the results
generated by C++ function are extended double precision. The comparison of different precisons caused some of those test cases
failed too.
This CL disables RunFloat64Sin/RunFloat64Cos/RunFloat64Expm1/RunFloat64Tan/Ieee754.Expm1/Ieee754.Cos/Ieee754.Tan test cases for x87.

Operand values in Bytecodes.DecodeBytecodeAndOperands test are encoded
in little endian format. The test calls Bytecodes::Decode function which
reads the operands but the values are byte swapped on big endian
machines. Added big endian encoded data which decodes correctly on BE
machines.

Because the operands in this test are encoded in little endian format.
Therefore, their bytes are all swapped when reading them on big endian machine.

Follow-up to 87db4ff1f4, which added
suppressions to unittests.status and a special case for Android to the
ThreadLocalStorageTest, both of which are unneccessary and should be
handled differently for the GTest based unittests.

cctest/test-threads/ThreadJoinSelf is suppressed for Android, but the
test has since been moved to unittests/Thread.SelfJoin. Move the
suppression to unittests.status.
unittests/ThreadLocalStorageTest.DoTest fails on older Android devices
as it assumes the availability of more TLS slots than many devices
implement. Test a smaller number of slots (32) on Android. Remove old
suppression of test-platform-tls/FastTLS (which no longer exists).
cctest/test-mark-compact/RegressJoinThreadsOnIsolateDeinit can't deal
with shared mappings. Check for 's' instead of '-'.
