These intrinsics are unused now, and so we can drop all the code in
fullcodegen and Crankshaft that deals with those. TurboFan and Ignition
never tried to optimize those.

This way we avoid the cyclic dependency between objects.h and heap.h and still
have one definition. Add a static assert that this size is indeed smaller than
the payload of a page.

Follow ups can finally remove the dependency on spaces.h for all heap.h users.

Now that all backends use the source position builder to record source
positions, simplify the code line logging events to take a source
position table on code creation. This means that the source position
table builder no longer needs to access the isolate until the table is
generated. This is required for off-thread bytecode generation.

Original commit message:

    One caveat: the Crankshaft stub used to preserve callee-clobbered double
    registers, which is contrary to any real platform ABI that we support. Since the
    only current use of this stub is in Crankshaft, the instruction there now must
    be marked as double-clobbering. This might result in a small performance
    regression. However, when this stub is eventually used in TF-generated code, it
    will be called from deferred code that can save doubles only on the rarely-taken
    path... something that Crankshaft can't do.

So far TurboFan wasn't adding the deoptimization reasons for eager/soft
deoptimization exits that can be used by either the DevTools profiler or
the --trace-deopt flag. This adds basic support for deopt reasons on
Deoptimize, DeoptimizeIf and DeoptimizeUnless nodes and threads through
the reasons to the code generation.

Also moves the DeoptReason to it's own file (to resolve include cycles)
and drops unused reasons.

named loads from explicit receiver. In addition, named loads does not

This switches Math.log to use an fdlibm based version of log, imported

When walking up the prototype chain during OrdinaryHasInstance, we first
check if the current prototype equals the expected one, and only
