Platform ports that use this RelocInfo kind need to implement
set_target_internal_reference accordingly to distinguish between
INTERNAL_REFERENCE and INTERNAL_REFERENCE_ENCODED.

We previously had two nested SCRIPT_SCOPEs (used to be GLOBAL_SCOPES), but as
the lexical variable implementation changed, the inner one is no longer needed.

Reduces the amount of custom support code for Math functions in TurboFan
and allows for more general inlining (i.e. independent of parameter
types).

Basically recognize certain x < y ? x : y constructs and turn that into
Float64Min/Float64Max operations, if the target machine supports that.
On x86 we lower to (v)minsd/(v)maxsd.

e8b9f2d7 introduced a different cast which broke building on Illumos.
Revert to previous behavior for V8_OS_SOLARIS only.
Found on SmartOS while building with gcc 4.9.0.
edit1: adding jochen to reviewers since he was assigned through the issue tracker and danno since he seems to do a fair amount of cross-platform work
edit2: removing BUG reference because I don't understand what LOG needs to contain (and it seems to link to chromium and not the v8 repo). Please edit commit message as appropriate.

This introduces a choke point in the AstGraphBuilder for property
access creation. This makes it easier to enrich all such nodes with
additional side-table or debugging information.

It should be possible to cast a Value to Int32 without throwing an exception
when IsInt32() is true. Same for Uint32.

We can reduce the number of type feedback vector slots required, and
also reduce IC misses.

A diamond is unused if the Merge node has no Phi/EffectPhi uses, exactly
two inputs, one IfTrue and one IfFalse, which have the same Branch
control input and no other uses except for the Merge. In this case the
diamond can safely be removed.

Since recursive modules are gone, only the top-level scope can have
module inner scopes. Rename Scope::AllocateModulesRecursively to
Scope::AllocateModules, and add test showing the module Variables
are still allocated appropriately in the top level scope.

The problem is that tagged slot could become a double slot after migrating of an object to another map with "shifted" fields (for example as a result of generalizing immutable data property to a data field).
This CL also adds useful machinery that helps triggering incremental write barriers.

Outside of runtime.h, only the distinction between intrinsics
returning pairs and those returning pairs is really meaningful, not
the internal traditional partitioning of them.

Combined the various lists, the only slightly ugly thing is now the
distinction between intrinsics returning pairs and the rest, but
that's no big deal.

I did some investigation and found that in the most cases
the old schema with the separate List for functions and inlines
gives us no memory benefits because more frequently we inlines
different functions into parent function. So the plain schema
wins a tens or even hundreds bytes a few thousand times.
The only drawback is that we will print the inlined body
the each time when we inline it. But is not a problem
because it happens only under FLAG_hydrogen_track_positions.
Also I added script_id to the structure, so it could be used later
by cpu-profiler.

The external v8::TryCatch handler was computed eagerly and kept in
intact. This changes it to be computed lazily for simplicity and
readability of the code.

Contribution of PowerPC port (continuation of 422063005,
817143002,866843003, and 901083004). This patch updates
the ppc directories to make them current with changes in
common code as of today.
We had to exclude the test test-serialize/SerializeInternalReference
until we agree on the right way to add those changes for PPC as
outlined in the description in the google doc provided earlier.
We also had to exclude a couple of other tests due to new
failures seen since the last uplevel. We excluded as opposed
to waiting until we could investigate to maximize the chance
of getting PPC compiling in the google repos before new
breaking changes are made.
I'll note that before applying any of our changes the
mozilla part of quickcheck was already broken when using
the lastest repo content so I had to run without that
