      [runtime] Drop redundant %CharFromCode runtime entry. · 2b4cb2a1
      bmeurer authored 
      The %StringCharFromCode and %CharFromCode runtime function perform
exactly the same task, so we need only one of them.

      [builtins] Introduce specialized Call/CallFunction builtins. · 7c3396d0
      bmeurer authored 
      Introduce receiver conversion mode specialization for the Call and
CallFunction builtins, so we can specialize the builtin functionality
(actually an optimization only) based on static information from the
callsite (this is basically a superset of the optimizations that were
available with the CallFunctionStub and CallICStub, except that these
optimizations are correct now).

This fixes a regression introduced by the removal of CallFunctionStub,
for programs that call a lot.

      [assembler] Introduce proper AssemblerBase::Print() for improved debuggability. · ab1d270a
      mtrofin authored 
      While working on frame elision, I wanted to disassemble codegen in the
debugger, as the code generation is progressing. I discovered we had a
 "Print" member on the x64 assembler, without any implementation. I
pulled it up to AssemblerBase and gave it an implementation that
should work for the other architectures.

Also checked that ia32, x87, arm and arm64 assemblers didn't have
such an implementation - free Print.

Arm64 has a naming conflict with the v8::internal::Disassembler. I
renamed the arm64 type with a more specific name.

Opportunistically fixed a bug in the name converter. This debug-time
printer doesn't provide a Code object, which should be OK with the
name converters, by the looks of other APIs there. All this means is that
when using the Print() API, we just get addresses dumped without any
context (like what this address may be - a stub maybe, etc). This seems
fine for the scenario.

There may be other places that assume a Code object. Since this is
a diagnostics-only scenario, for codegen developers, I feel it is
reasonable to fix such other places as we find them.
