ARM: Do not set FPSCR when converting to clamped uint8
Setting the FPSCR flags is expensive on some CPUs. Get rid of repeated
setting of the FPSCR by relying on the correct default flags being set
when doing uint8 clamping. Also use vcvt_u32_f64 instead of vcvt_s32_f64,
which enables removing the check against zero (vcvt_u32_f64 will clamp to
zero).
To be on the safe side, add asserts to check that the VFP rounding mode
flags are set to default as expected.
This increases performance of a hot loop repeatedly setting
Uint8ClampedArray values on some CPUs by as much as a factor of 12.

Use abstract configurations to switch between opt debug settings
The problem is that conditions are evaluated before configuration inheritance is resolved, so we can't just define a configuration like this:
'Optdebug': {
'inherits_from': ['Debug'],
'variables': {
'v8_optimized_debug': 2,
}
}
Instead, we have to put the different settings depending on the optimization level into separate configurations, and use conditions inside the concrete configurations to inherit from the correct base class.
Common settings go in the base configuration DebugBaseCommon, and v8_optimized_debug dependent settings go into DebugBase{0,1,2}
The new Debug configuration inherits from DebugBaseCommon and DebugBase<(v8_optimized_debug), while the new configuration Optdebug inherits from DebugBaseCommon and DebugBase2.

ARM64: Put all simulator trace on the same stream.
The simulator can trace to a specified stream, typically stderr or
stdout. However, several messages (such as ASM_LOCATIONs) were printed
only to stdout. As a result, they often ended up out of order with
respect to the instruction trace. This patch causes all simulator output
to go to the same stream.

Ensure that we don't mark weak heap references in the constant pool array.
Some heap pointer's embedded in optimized code are considered weak. Ensure
that we don't mark them during GC of the ConstantPoolArray. Also, embed
