and TurboAssembler. Instead of listing all the different combinations of arguments (which is one more now, temporarily), just forward all arguments down via MacroAssembler and TurboAssembler to TurboAssemblerBase.

This CL replaces most uses of the V8_EMBEDDED_BUILTIN define by a new read-only runtime flag called FLAG_embedded_builtins. The flag is true iff V8_EMBEDDED_BUILTINS is defined.

We had a kRootRegisterBias on x64 before. This CL ports the feature to all other platforms as well. The root register bias is helpful to adjust the value of the root register, which allows to better utilize signed immediate offset constants in load instructions. We currently use a separate add instruction to add kRootRegisterBias in the code that initializes the root register. This could be improved by adding a custom relocation mode ensuring that instead of the root address, the root address plus the bias is inserted (and in this way the add instruction can be omitted).

This CL attempts to simplify the Assembler's dependency on the isolate, in particular on a global "serializer_enabled" mode contained therein. The "serializer_enabled" condition enabled and disabled a number of things in both the assemblers and macro assemblers. To make these dependencies explicit, the Assembler::IsolateData is refactored to be a proper Assembler::Options struct that controls specific assembler behaviors, with default settings easily computable from the isolate. This also helps make the contract for compiling WASM code more explicit (since WASM code needs to have reloc info recorded for external references) we can explicitly enable this recording without trying to "trick" the assembler using "serializer_enabled".

Indirections for external references are now handled completely in macro assemblers, which can produce more efficient code.

External references located within the isolate can be loaded as a fixed offset from the root register. This avoids one load from memory over the default indirect method (which reads from the external reference table).
