Introduce a stripped down version of UseScratchRegisterScope for ARM and use it inside the assembler and macro-assembler. At the exception of the Call instructions, we now use this scope instead of using the ip register directly. This is inspired from how the ARM64 backend works. In general, the benefit of doing this is we can catch cases where ip is being used both by the caller and by the assembler. But more specifically, TurboFan reserves r9 as an extra scratch register because ip can already be used by the assembler. With this utility, we can isolate the cases in the code generator which need an extra register and potentially fix them, allowing us to give r9 back to the register allocator. This patch uncovered places in the assembler where we were using ip unconditionally when we could have re-used the destination register instead.

On x86, signalling NaNs get converted to quiet NaNs when they get push on the stack and popped again. This happens in the code generation for arm, specifically for the vmov instruction with the immediate parameter. This CL replaces the vmov function in assembler-arm to take the immediate as a uint64_t instead of a double, to guarantee that the bit pattern does not change even if the parameter is a signalling NaN.

Instead of counting profiler ticks on the shared function info (which is shared between native contexts), count them on the feedback vector (which is not). This allows us to continue pushing optimization decisions off the SFI, onto the feedback vector. Note that a side-effect of this is that ICs don't have to walk the stack to reset profiler ticks, as they can access the feedback vector directly from their feedback nexus.

v8.cpu_profiler has a long and variable warm up period. If you look in tracing that time shows up under V8.Execute which is very misleading. By adding a tracing category for the time spent in CpuProfiler::StartProfiling the warm up time can be easily identified or even filtered out. With this tracing event the block in StartProfiling correctly described the time spent prepare v8.cpu_profiler out from V8.Execute Test by collecting a trace with V8.Execute and look at when a trace starts generating v8 samples.
