Promise.{all,allSettled,any,race} should check resolve is a function before opening their iteratable. PR: https://github.com/tc39/ecma262/pull/1912 PR for Promise.any: https://github.com/tc39/proposal-promise-any/pull/65 This CL includes the following cleanup changes: - Made it more explicit that the constructor is a Constructor. - Removed unnecessary nested try blocks (a try can have both a catch and a label). - Moved commonly used definitions out of promise-race.tq where they don't belong. - Made the parameter order of PerformPromiseAll match the spec.

The {NONE} reloc info is the one used most often, i.e. for every assembler call that takes an {Immediate} on x64 which is not relocatable. Hence assign value 0 to {NONE} such that constructing such immediates is faster and also checking for this most common case is faster.

Avoid going through the {WasmDebugInfo}, which existed for debugging in the interpreter in production. Instead, tests now instantiate the interpreter directly. This will unblock the removal of the whole {WasmDebugInfo}, and finally moving the interpreter to the test directory.

The reference stack was set by the scope, and reset when leaving the scope, in order to avoid leaking objects via cycles in the reference tree, involving global handles which are considered strong roots. Since the interpreter cannot call out to JS any more, we cannot create such cycles any more. Hence, the ReferenceStackScope is removed, and the FixedArray for the reference stack is allocated as a global handle instead. This will unblock removing the WasmDebugInfo object, which was used by the ReferenceStackScope before this CL.

Fix dcheck failure where committed was smaller than used memory. This was because of background threads allocating between calculating both stats and used memory could already be larger due to those background allocations. Avoid this first calculating used memory and committed memory afterwards.

A previous CL removed the kNoThrow flags from both SpeculativeBigIntAdd and SpeculativeBigIntSubtract. This introduced a bug, because the JSTypeHintLowering phase, where these operators are introduced during inlining, does not support the generation of throwing operators. Since these operators always deoptimize in case of an error, instead of throwing the exception directly, it is safe to mark them as kNoThrow.

Adds allocation-based heap growing strategy that triggers GC based on some limit. The limit is computed based on previous live memory and a constant growing factor. For invoking GC, we support two modes: with and without conservative stack scanning. Without conservative stack scanning, an invoker makes sure that we schedule a GC without stack using the existing platform.
