Revert r23732 ("ARM64: Fix and improve --trace-sim register trace.") and r23733 ("ARM64: Fix build warning in r23732.)

They break the build when compiling with optimizations, e.g. optdebug:

../src/arm64/simulator-arm64.cc: In member function ‘void v8::internal::Simulator::PrintWriteFP(uintptr_t, size_t, unsigned int)’:
../src/arm64/simulator-arm64.cc:792:29: error: array subscript is above array bounds [-Werror=array-bounds]
../src/arm64/simulator-arm64.cc:799:29: error: array subscript is above array bounds [-Werror=array-bounds]

[turbofan] Fix the node matchers.

E.g. make sure that Int32Matcher matches only int32 constants, and
Float64Matcher matches only float64 constants.

Also remove the confusing CommonOperatorTraits, which are too easy
to use in a wrong way.

To aid vector-based load ic work, we need to be able to handle
the megamorphic load case in hydrogen. A simple approach is to
wrap the probe activity in a hydrogen instruction.

The instruction is novel in that it always tail-calls away.
