Calculate the number of bytes of the stack frame used in PatchPrepareStackFrame using the size of the spill instead of the number of slots. We only need the number of bytes spilled (without adding the number of locals) because whenever we spill, we already track the largest offset, with RecordUsedSpillSlot. GetTotalFrameSlotCount can also be changed to remove the num_locals, in a future patch.

When converting a Smi to a String, we can skip the check for a cached array index on the result in case of a number-to-string cache hit. When trying to convert a String back to an index, the inlined fast path can check for a cached index (in addition to checking for a cached known negative). Locally this yields about 5% on the JSTests/Proxies/GetIndex* tests.

Loop variable analysis doesn't recognize that the initial type of the loop variable phi combined with the increment type may produce a NaN result through the addition of two infinities of differing sign. This leads to unreachable code and a SIGINT crash. The fix is to consider this case before typing the loop variable phi, falling back to more conservative typing if discovered.

All counters have the same name as the phase name with the v8.TF prefix replaced with Optimize. To enforce this, the existing phase_name declaration in each phase has been replaced with a macro that also declares the counter id and its mode.

Import wrappers (wasm-to-js) were missing from profiling, since their code is never logged. This CL fixes this by generally logging all wasm code generated, not just actual wasm functions. Also, instead of logging each individual code object (which requires a lock) within another lock, move the code out of the other lock and log all code objects at once.

This fixes a few thing regarding code logging for profiling: 1) Append the execution tier, otherwise we get two function of the same name. 2) Replace "wasm-function[%d]" by "<wasm-unnamed>", since the index is appended later anyway. 3) Avoid unneeded JS heap and C++ heap allocations during logging.

Design doc: bit.ly/v8-repl-mode This CL allows the usage of 'await' without wrapping code in an async function when using REPL mode in global evaluate. REPL mode evaluate is changed to *always* return a Promise. The resolve value of the promise is the completion value of the REPL script. The implementation is based on two existing mechanisms: - Similar to async functions, the content of a REPL script is enclosed in a synthetic 'try' block. Any thrown error is used to reject the Promise of the REPL script. - The content of the synthetic 'try' block is also re-written the same way a normal script is. This is, artificial assignments to a ".result" variable are inserted to simulate a completion value. The difference for REPL scripts is, that ".result" is used to resolve the Promise of the REPL script. - ".result" is not returned directly but wrapped in an object literal: "{ .repl_result: .result}". This is done to prevent resolved promises from being chained and resolved prematurely: > Promse.resolve(42); should evaluate to a promise, not 42.
