We move the implementation in Liftoff (which is the most general and handles AVX/SSE and also register aliasing) into shared-macro-assembler. Also consolidate SSE/AVX for ia32. No functionality change is expected.

This unblocks https://crrev.com/c/3099011 by speeding up the case for the DebugPropertyIterator where only non-indexed properties (for large arrays or typed arrays) are requested. Previously we'd walk through all properties - including all indexed properties - and only filter out the indexed properties in the end in `ValueMirror::getProperties()`.

The refactoring is triggered by https://crrev.com/c/3121905 where we noticed that a bunch of tricky counter paths could be simplified, making reasoning about corectness easier. In this CL: 1. Use uniqe_ptr instead of Optional to allow moving SweepingJob away from the header file. 2. sweeping_in_progress_ is replaced with simply checking for a job. 3. freed_bytes_ are moved to the job and the dependency is reversed, avoiding the inside-out (Job->Sweeper) dependency completely. 4. Merge() and counter updates are merged into a Finalize() method. 5. FinishIfDone() allows for conditional finization. 6. young_bytes_ and old_bytes_ are removed as they were always updated when the corresponding bytes in the ArrayBufferList was updated.

No asymptotic improvements, and none are planned either. Minor speedups (25-50%) through reduced overhead: accessing Digits is faster than working with Handle<BigInt>, and this implementation avoids allocating intermediate results.

In https://crrev.com/c/3131374 we switched some instructions to use macro-assembler functions which can handle AVX and SSE. However for Cvtsi2ss and Cvtsi2sd, the behavior subtly changed. The old behavior directly called cvtsi2ss/cvtsi2sd in the code-generator. The new behavior used the macro-assembler functions, which xor the dst operand. This led to more instructions and larger code size in some benchmarks. The xor is supposed to help reduce dependence chain length (see comments on Cvtsi2ss), but doesn't seem to have helped in this benchmark. So, partially revert the changes, and rename all affected IA32 opcodes back to SSE.

Move some AVX_OP into shared macro-assembler, for reuse by ia32 in future patches. Movlhps is also unused in x64, so remove it. Drive-by cleanup to use macro assembler helper Move to move 128-bit const into a XMMRegister. The change in liftoff-assembler-x64 is required because now the macro-assembler functions are defined in the base class, so even though we can use &TurboAssembler::Pcmpeqd to refer to that member function, it actually resolves to &SharedTurboAssembler::Pcmpeqd.

The {CountClearHalfWords} method is called whenever loading a constant into a register. It showed up with >0.5% in Liftoff compilation profiles. This CL refactors the method to return the number of *set* halfwords instead of *cleared* halfwords and avoids the loop in the implementation. This makes the method roughly twice as fast, and makes the code more readable.

If background threads are tiering up, they could temporarily make code writable (if using the mprotect based approach). This would make our death tests fail (i.e. not crash). This CL fixes that by repeatedly writing in that case. Eventually, the code should be protected again, and then we would crash. Failure to crash would manifest as a timeout of the tests.
