... and add explicit CallPrologue/CallEpilogue callbacks to CodeAssemblerState instead.
This will allow IntepreterAssembler to use any other helper assembler.

This is in preparation for introducing more specialized
CodeStubAssembler subclasses. The state object can be handed
around, while the Assembler instances are temporary-scoped.

Reason for revert:
https://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20shared doesn't want to compile. Missing export annotation?

This removes some compiler internals as well as some JavaScript specific
helper from the CodeAssembler, by either hiding or moving the support
into the CodeStubAssembler.

Anotates bytecodes with a description of how each uses the accumulator.
Validates annotations and uses of accumulator when generating bytecode
handlers.
Only prints the accumulator during tracing where used.

This change introduces wide prefix bytecodes to support wide (16-bit)
and extra-wide (32-bit) operands. It retires the previous
wide-bytecodes and reduces the number of operand types.
Operands are now either scalable or fixed size. Scalable operands
increase in width when a bytecode is prefixed with wide or extra-wide.
The bytecode handler table is extended to 256*3 entries. The
first 256 entries are used for bytecodes with 8-bit operands,
the second 256 entries are used for bytecodes with operands that
scale to 16-bits, and the third group of 256 entries are used for
bytecodes with operands that scale to 32-bits.

Moves InterpreterAssembler out of the compiler directory and into the
interpreter directory. Makes InterpreterAssembler as subclass of
CodeStubAssembler.
As part of this change, the special bytecode dispatch linkage type
is removed and instead we use a InterfaceDispatchDescriptor and
a normal CodeStub linkage type.
Removes a bunch of duplicated logic in InterpreterAssembler and
instead uses the CodeStubAssembler logic. Refactors Interpreter
with these changes.
Modifies CodeStubAssembler to add the extra operations required
by the Interpreter (extra call types, raw memory access and some extra
binary ops). Also adds the ability for subclasses to add extra
prologue and epilogue operations around calls, which is required
for the Interpreter.
