Original commit message:
Also, CodeGenerator::MakeCodeEpilogue now accepts an optional pointer
to a EhFrameWriter and will attach unwinding information to the code
object when passed one.
Reason for reverting:
The STATIC_CONST_MEMBER_DEFINITION in eh-frame-writer-unittest.cc
causes a compiler error on V8 Win64 - clang buildbot.
Removing that bit.

Import base::ieee754::exp() from FreeBSD msun and introduce a Float64Exp
TurboFan operator based on that, similar to what we do for Float64Log.
Rewrite Math.exp() as TurboFan builtin and use that operator to also
inline Math.exp() into optimized TurboFan functions.

We still share the code globally, but if we wanted, it would be easy to
make it per isolate now

This enables linter checking for "readability/namespace" violations
during presubmit and instead marks the few known exceptions that we
allow explicitly.

Speculative revert in the hopes of fixing serializer crashes seen in canary.
This reverts commit c166945083, as well as
followup change "Do not look for existing shared function info when compiling a new script."
(commit 7c43967bb7).

Each Script object now keeps a WeakFixedArray of SharedFunctionInfo
objects created from this script.
This way, when compiling a function, we do not create duplicate shared
function info objects when recompiling with either compiler.
This fixes a class of issues in the debugger, where we set break points
on one shared function info, but functions from duplicate shared function
infos are not affected.

It was only used for Math.log, and even then only in full code and in %_MathLog. For crankshafted code, Intel already used the FP operations directly, while the ARM/MIPS ports were a bit lazy and simply called the stub. The latter directly call the C library now without any cache. It would be possible to directly generate machine code if somebody has the time, from what I've seen out in the wild it should be only about a dozen instructions.

This is just a rename change with the exception of a bug found along the way in
CodeStubGraphBuilder<FastCloneShallowArrayStub>::BuildCodeStub(). There, the
intent is to get the boilerplate object from an AllocationSite. But the wrong
HObjectAccess was used. It only succeeds because it happened to be the same
offset :).
