v8::String::IsExternal which returns true for both, external one-byte and

Add a Utf16CharacterStream for windows-1252, which uses a table to
covert from windows-1252 to the appropriate uc16 character. This fixes
issues where windows-1252 encoded source was treated like latin-1.

This introduces a new encoding type in the API, so embedders will have
to opt-in to using this new stream.

Be explicit about source positions for `Return`s in the
BytecodeGenerator, and only do self-healing explicitly in the
`ReturnStatement` translation, where an end position of
`kNoSourcePosition` is turned into the return position of the
function literal.

This allows us to reason more easily about which `Return`s actually
receive a meaningful source position, and in particular it allows us
to construct the internal `Return`s for `yield` and `yield*` with no
source position attached to them. Previously they'd get the source
position for the implicit (final) return attached to it, which confused
the debugger and led to breakpoints being set in the completely wrong
spot.

Considering the simplified example

```
function* foo(){
  var a = 1;
}
```

this would previously generate the following bytecode

```
        0 : SwitchOnGeneratorState r0, [0], [1] { 0: @20 }
        4 : Mov <closure>, r2
        7 : Mov <this>, r3
 13 E> 10 : InvokeIntrinsic [_CreateJSGeneratorObject], r2-r3
       14 : Star0
 13 E> 15 : SuspendGenerator r0, r0-r1, [0]
       20 : ResumeGenerator r0, r0-r1
       24 : Star2
       25 : InvokeIntrinsic [_GeneratorGetResumeMode], r0-r0
       29 : SwitchOnSmiNoFeedback [1], [2], [0] { 0: @39, 1: @36 }
       33 : Ldar r2
 13 E> 35 : Throw
       36 : Ldar r2
 30 S> 38 : Return    <=========================== internal Return
 27 S> 39 : LdaSmi [1]
       41 : Star1
       42 : LdaUndefined
 30 S> 43 : Return
```

where everything between offset 4 and 42 corresponds to the implicit
yield at the beginning of every generator function, in particular the
code between 20 and 42 corresponds to that initial yields resumption
logic. Notice how the internal Return at offset 38 gets assigned the
source position of the function literal (the same as the implicit
return at the end). This confuses the debugger quite a bit when trying
to set a breakpoint on the closing brace, since it's going in bytecode
order and will thus discover the `Return` at offset 38 first (matching
the source position 30 it's currently looking for) and setting the
breakpoint there. This `Return` bytecode however is only executed when
the generator is resumed via `GeneratorPrototype.return()`, and it'll
not hit when the developer uses the generator normally, which is not
the desired behavior and extremely confusing (especially since stepping
on the other hand works as expected).

With this patch, we no longer slap a source position (and in particular
not the function literal's return position) onto these internal
`Return`s as you can see from the generated bytecode below:

```
       0 : SwitchOnGeneratorState r0, [0], [1] { 0: @20 }
       4 : Mov <closure>, r2
       7 : Mov <this>, r3
13 E> 10 : InvokeIntrinsic [_CreateJSGeneratorObject], r2-r3
      14 : Star0
13 E> 15 : SuspendGenerator r0, r0-r1, [0]
      20 : ResumeGenerator r0, r0-r1
      24 : Star2
      25 : InvokeIntrinsic [_GeneratorGetResumeMode], r0-r0
      29 : SwitchOnSmiNoFeedback [1], [2], [0] { 0: @39, 1: @36 }
      33 : Ldar r2
13 E> 35 : Throw
      36 : Ldar r2
      38 : Return
27 S> 39 : LdaSmi [1]
      41 : Star1
      42 : LdaUndefined
30 S> 43 : Return
```

This also allows us to remove the break position finding hack that was
kept in BreakIterator::BreakIndexFromPosition() for generators and
modules.

The main problem here is that the macro-assembler for Pmaddubsw and
Pmaddwd expects dst == src1 when AVX is not supported.

For Pmaddwd, we use an existing macro to define the function.

For Pmaddubsw, we do the AVX check inline and use movaps if not
supported because it requires a SSSE3 scope, and we don't have an
existing macro to do this (we can find other uses and clean up as
necessary in the future).

v8_libsampler was previously split off to serve goals that were never
achieved and seem unlikely to be. Since the division creates a
dependency cycle between v8_base_without_compiler and v8_libsampler
(where one edge is a #include that breaks gn check), this moves
sampler.* back into v8_base_without_compiler and removes the
v8_libsampler target.

Split out all the headers from v8_compiler/v8_compiler_opt and
v8_base_without_compiler into v8_internal_headers since the headers
have inter-dependencies that otherwise make it impossible to satisfy gn
check.

Also adds new v8_header_set torque_runtime_support that exports
src/torque/runtime-support.h separately from the generated headers.

This reduces the number of gn check failures from 169 to 59.

Using Parameter has some crashes on arm64. The other Parameters are
also using UncheckedParameter so let's use that.

This CL removes the includes of src/wasm files from the API if Wasm is
disabled (v8_enable_webassembly=false). This will allow to later
remove the whole src/wasm directory from compilation.
Since we do not want to modify the exposed API in a no-wasm build, we
instead make all Wasm-related functions fail.

This CL is part of a series that adds the C++ implementation of
SwissNameDictionary, a deterministic property backing store based on
Swiss Tables.

This CL adds an in-place version of Rehash and a small change to
HeapObject::HeapObjectShortPrint.

We got a TSAN
warning because of the non-atomic store of the code pointer in
a JSFunction in the interpreter builtin (when the pointer is
discovered in the FeedbackVector). However, we know this store is
safe because we guarantee a release store into the
FeedbackVector. However, TSAN can't recognize this interesting
triple relation. Therefore, we mark the fields we need to read
from TurboFan as relaxed.
