... when external code space is enabled.

Since we are using near jump/call instruction only for [tail]calling
builtins, we can increase the code range as long as we can guarantee
that the remapped builtins are always reachable. We can do that by
remapping embedded builtins into the middle of the code range.

Similar to https://crrev.com/c/3634781, this switches some {BitVector}s
in the regular top-tier register allocator to {SparseBitVector}. For
functions with a huge amount of virtual registers, this would save a
significant amount of memory, and also performance.

For small number of registers though we probably introduce a slight
regression, because there is one more dynamic check to be performed
before accessing the bits.

This refactors ConvertToRelativeIndex into a clamping version and a
version that takes OOB labels for the upcoming implementation of
Array#with and TypedArray#with.

Also gets rid of the the "to" in the name, because these macros are
actually converting _from_ a relative index to an absolute one, not
the other way around.

We introduce wasm types to Turbofan. They are represented by a new
subtype of {TypeBase}.
Types are attached to nodes during graph generation, as nodes are
assigned to wasm values. Therefore, phi nodes corresponding to merges
are not typed. Missing types will be computed, and assigned types will
be narrowed as much as possible, in a retyping phase that will be
introduced later.

StoreHandlers can store either a Code object or a Smi, so the
smi_handler field on DataHandler is a Code|Smi. But, LoadHandlers can
only store Smis here so add a shadowing smi_handler definition which
only allows / returns Smis.

The cctest test-code-generator/FuzzAssembleMove fuzzes codegen
for a random list of sequential moves by simulating the moves on a
FixedArray, and comparing the result to the output of the generated
code.

Add a variant of this test that resolves parallel moves first, to also
test integration with the gap resolver.
