Generate the code (extra runtime calls) for --trace-ignition support at compile time, based on a #define (similar to TRACE_MAPS). Then check for --trace-ignition at run-time when deciding whether to actually print anything. This should make --trace-ignition less painful to use. Note that --trace-igition is disabled by default, even on debug builds. It has to be enabled with the gn arg "v8_enable_trace_ignition=true" As a drive-by, TRACE_MAPS is renamed to V8_TRACE_MAPS, for consistency, and SFI unique index (needed both by --trace-ignition and --trace-maps) is cleaned up to be behind another #define.

Reland d8bfdb7a Original commit message: If alignment parameter is set, the memory returned by the StackSlot operator will be aligned according to the parameter. The implementation goes like this. If alignment parameter is set we allocate a bit more memory than actually needed and so we can move the beginning of the StackSlot in order to have it aligned.

Unify, simplify logic, reduce UTF8 specific handling. Intend of this is also to have stream views. Stream views can be used concurrently by multiple threads, but only one thread may fetch new data from the underlying source. This together with unified stream view creation is intended to be used for parse tasks.

When most elements of an object are deleted, we want to normalize its elements backing store to a dictionary in order to save space. Finding the right time to do so should not incur a linear cost on each delete operation. This patch changes the heuristic to an amortized-constant approach based on a global counter and the current backing store capacity.

Now that the optimized code hangs off the feedback vector, it is possible to check whether a function has optimized code available every time it's called in the interpreter entry trampoline. If optimized code exists, the interpreter entry trampoline 'self-heals' the closure to point to the optimized code and links the closure into the optimized code list.

We currently grow the backing store to (old_capacity*1.5)+16 if we exceed capacity, but shrink the capacity to the current length when 2*length <= capacity. For short arrays (up to length 32), this can lead to a copy on every operation when using push/pop or push/shift. Example: Array of length 32, capacity 32 push Array grown to length 33, capacity 32*1.5+16 = 64 pop Array trimmed to length 32, capacity 32 because 2*32 <= 64 ... This CL leaves additional slag space when calling pop and restricts the trimming to backing stores with at least 16 elements to prevent excessive re-trimming on short arrays.

Split BytecodeGenerator::VisitSuspend into two pieces, one for building the suspension code and one for resumption (these are split into separate Build methods for convenience). Each gets its own RegisterAllocationScope, which allows us to reduce the register file size of the empty generator by 1. For consistency, rename VisitGeneratorPrologue() to BuildGeneratorPrologue() to match the names of the two newly-created methods.
