This patch replaces V8's tracing implementation (i.e., the TRACE_EVENT macros) with the track event base implementation from Perfetto. The advantages of doing this are: 1) This allows us to remove most tracing-related backend code from V8. 2) V8 can start writing strongly typed trace event arguments, which are more compact, easier to process and more extensible than legacy JSON-based trace arguments. For the time being, we still support the old trace macros when V8 is embedded into Chrome and other embedders.

{StaticCharVector}, according to its name, should return a {Vector<const char>}. For getting a {Vector<const uint8_t>}, the method should be called {StaticOneByteVector}, analog to the {OneByteVector} methods that already exist. Also, {StaticCharVector} is constexpr, but {StaticOneByteVector} cannot be, since it contains a {reinterpret_cast}. The same holds for {Vector::cast} in general. This CL - changes the return type of {StaticCharVector} to be {Vector<const char>}, - introduces a new {StaticOneByteVector} which returns {Vector<const uint8_t>}, - fixes constexpr annotations at various methods returning {Vector}s, - refactors users of {StaticCharVector} to either use {StaticOneByteVector} instead, or work on {char} if that makes more sense.

Even though {Factory::InternalizeString} was declared as a template, only two instantiations exists: uint8_t and uint16_t. Using any other type leads to link-time errors, which is inconvenient. This CL implements the two instantiations explicitly, and provides a third implementation taking a {Vector<const char>}. This will be used after the next CL, which changes {StaticCharVector} to actually return a {Vector<const char>}. This also avoid the cumbersome template exports.

This adds another enum value in the {ForDebugging} enum for stepping code. By not adding the code to the code table and jump table, we will never execute this code via a wasm function call. The code will only be used for the one frame where we want to step through. This speeds up stepping over recursive calls enormously, since the recursive calls don't run into the flooded breakpoints any more. It also fixes issues with non-local control flow, i.e. catching a trap and reentering the same wasm function.

Stepping only happens in one frame at a time, so we don't need to rewrite the whole stack. This allows us to remove the {flooded_function_index_}, since no function is globally flooded any more. A follow-up CL will ensure that the code will also not be installed in the code table and jump table any more, to fix issues with non-local control flow (i.e. catching a trap and reentering wasm), where we could currently accidentally execute flooded code. It will also speed up stepping over recursive calls enormously, since the recursive calls don't run into the flooded breakpoints any more.

GAS have a auto-align function which will align all the directive data into it's nature boundary. And we're using .octa to present data in embedded.S, which will be auto-aligned into 128-bit boundary. It can break relatve offset in generated binary. So we workaround it by forcing generate .long DataDirective on MIPS. Also I rewoked WriteByteChunk so it can accept any kind of directive now. Further more, implementation of HexLiteral is indentical on generic, aix and mac so I merged them into base.

Instead of putting the 16 immediate bytes on the stack, we move them into a temporary register. The instruction-selector then has to change, to ensure that the operands are distinct from the temporary. Tested on the two workloads given in https://github.com/zeux/wasm-simd/issues/2#issuecomment-614399004 For slow, the row "filter:" oct12 goes from ~50ms to ~27ms, the rest of the figures look about the same or slightly faster. For optimal, the same figure goes from ~25ms to ~24ms, the rest of the figures look slightly faster. Raw outputs are uploaded to bug.

SIMD opcodes consist of the prefix byte, then an LEB128 encoded int. We were decoding this incorrectly as a fixed uint8. This fixes the decoder to properly handle multi bytes. In some cases, the multi byte logic is applied to all prefixed opcodes. This is not a problem, since for values < 0x80, the LEB encoding is a single byte, and decodes to the same int. If the prefix opcode has instructions with index >= 0x80, it would be required to be LEB128 encoded anyway. There are a bunch of trivial changes to test-run-wasm-simd, to change the macro from BUILD to BUILD_V, the former only works for single byte opcodes, the latter is a new template-based macro that correct handles multi-byte opcodes. The only unchanged test is the shuffle fuzzer test, which builds its own sequence of bytes without using the BUILD macro.
