Simple experiment that prefers free registers that are not used for arguments to prevent cases where we allocate a free register without hint and thereby block later uses of that register for no good reason.

Previously we'd always push variable proxies into the unresolved list of the current scope, and possibly delete them from the list later in case they end up being declarations. If variables become assigned, there were two ways to mark them as such: The preparser would marked the variables tracked on the PreParserExpression, and the parser would traverse the LHS AST to find and mark all variables. After this CL, if the scope already knows it's tracking declarations, the variables are never added to the unresolved list in the first place. If the scope is ambigous, it tracks the variable proxies on the side and only adds them to the unresolved list if they end up being references rather than declarations. The same list is now used to bulk mark all LHS variables as assigned; uniformely for both the parser and the preparser. In a next step we'll also use the scope to create declarations. That way we can stop tracking variables_ on PreParserExpression altogether.

This CL adds support for anyref in WebAssembly.Global objects. Note that the specification is not complete yet in this area. I did the following changes: - I renamed the `array_buffer` field of WasmGlobalObject to `untagged_buffer` - I added an additional field of type FixedArray, `tagged_buffer`. - In the constructor of WasmGlobalObject I allocate either the former or the latter, but not both. - In the WebAssembly.Global constructor I added special handling for the case where no initial value is provided. In that case I set the inital value to `null` and not to `undefined`.

On ia32, the instruction selector uses movsx_b to compile the wasm SignExtendWord8ToInt32 instruction. movsx_b requires a byte register as input. However, not all allocatable registers on ia32 are. As we cannot currently express constraints on subsets of registers, this change now forces the input to movsx_b into eax.

This CL prevents redundancy elimination from widening types, which can cause problems if the input of a DeadValue (which has type None) is replaced by an equivalent node that does not have type None. This can happen because load elimination does not re-type nodes, for example.

|argc| parameter of JSEntry is passed as int from C++ code, and loaded into a register on the asm code. As int is 32 bit, and registers are 64 bit on 64 bit platforms, upper 32 bits of the loaded value may be contaminated by a random value if it's passed as a stack parameter. For now, |argc| is passed as a register parameter on all platforms, and the upper 32 bits of |argc| is filled by zero, fortunately. However, if we shuffle the order of parameters, |argc| can be passed as a stack parameter and its value may be broken. Specifically on x64 Windows, the first 4 parameters are passed as register parameters and the rest are stack parameters. As |argc| is the 4th parameter, if we prepend another parameter and shift |argc| to the 5th parameter, |argc| will become a stack parameter and its load to 64 bit register breaks the value. This CL converts the type of the |argc| parameter to intptr_t, so that it's safe to load from stack to full width registers.

We currently hold the register list for {move_src_regs_} in the {StackTransferRecipe} class, and only compute src use counts for executing the moves. Since the use counts and the register list are redundant, just compute the use counts right away, and get rid of the register list. This saves one iteration of the register list in {ExecuteMoves}.

This queue is used for transferring tick samples between the foreground thread which creates them and the background thread which processes them. I've tested this on the node server example that we are using to measure memory use and found that we never fill the queue at this size. The load factor of the queue is basically a measure of how fast the producer pushes to it and how fast the consumer processes samples from it. To load test the configuration a bit I reduced the sampling interval from 1000us (1000 samples/sec) to 50us (20,000 samples/sec). At this rate we still only use 196/251 available slots in the queue at peak load (measurement taken by keeping a running max of #slots used, taken at StartEnqueue()). The default sampling interval is 1000us. 512 KiB ought be enough for anybody!
