de8cac4450 Make GCTracer persistent. 
This is essentially https://codereview.chromium.org/390823003/. It turns
out that it's safe to use a persistent GCTracer instead
of creating and destroying GCTracers for each GC, because
Scavenge and Mark-Sweep steps never overlap, and the tracking of
incremental marking also happens separately for the two types of GC.
Tracking of incremental marking will be moved into the GCTracer in a
follow-up patch.

1b5848c210 Some fixes to avoid breakages when enabling out-of-line constant pools. 
Three fixes which are required to pass all the tests when  out-of-line constant
pools are enabled for Arm:

 - Invalidate embedded objects in optimized code when it is deoptimized such
   that the weak pointers in the constant pool array are cleared.  This prevents
   a CHECK(heap_->mark_compact_collector()->IsMarked(object)) error when a
   verifying weak pointers in a deoptimized code object's constant pool.
 - Modify LargeObjectSpace::Verify to allow constant pool arrays in the
   large object space.
 - Increase the 32bit stack size limit, since the constant pool pointer
   is now on every stack frame, causing the size of each stack frame to
   increase by one word, and causing deep-recursion-test to fail.

e6936f2145 Reland "Remove erroneous uses of CXX / CXX_target / CXX_host from gyp." 
The current gyp config tries to test whether the compiler is an arm / mips
compiler and whether it supports -m32 / -m64 based on a test within gyp.
Unfortunately CXX / CXX_target / CXX_host are no no longer set early enough
in gyp for this to work, and so all of these tests were actually being done
using "$(which g++)" rather than the appropriate CXX_target / CXX_host compiler.

This change removes these dynamic tests and instead bases the decisions on
knowledge of the host / target / v8_target architecture combination.  The
the -m32/-m64 flags are set based on host_cxx_is_biarch / target_cxx_is_biarch,
which are set to reasonable defaults of only ia32/x64 or clang compilers
being build for biarch support.  The host_cxx_is_biarch / target_cxx_is_biarch
variables can be overriden if required.

e36f1dde46 Remove hole handling since holes cannot occur in JSObjects anymore. 
The only case in which the hole can still occur, is in a pre-allocated PropertyCell in a GlobalObject. In that case it indicates that the property is absent.

a42612b4a7 Change ScriptCompiler::CompileOptions to allow for two 'cache' modes 
(parser or code) and to be explicit about cache consumption or production
(rather than making presence of cached_data imply one or the other.)

Also add a --cache flag to d8, to allow testing the functionality.

-----------------------------
API change

Reason: Currently, V8 supports a 'parser cache' for repeatedly executing the same script. We'd like to add a 2nd mode that would cache code, and would like to let the embedder decide which mode they chose (if any).

Note: Previously, the 'use cached data' property was implied by the presence of the cached data itself. (That is, kNoCompileOptions and source->cached_data != NULL.) That is no longer sufficient, since the presence of data is no longer sufficient to determine /which kind/ of data is present.

Changes from old behaviour:

- If you previously didn't use caching, nothing changes.
Example:
  v8::CompileUnbound(isolate, source, kNoCompileOptions);

- If you previously used caching, it worked like this:

  - 1st run:
  v8::CompileUnbound(isolate, source, kProduceToCache);
  Then, source->cached_data would contain the
  data-to-be cached. This remains the same, except you
  need to tell V8 which type of data you want.
  v8::CompileUnbound(isolate, source, kProduceParserCache);

  - 2nd run:
  v8::CompileUnbound(isolate, source, kNoCompileOptions);
  with source->cached_data set to the data you received in
  the first run. This will now ignore the cached data, and
  you need to explicitly tell V8 to use it:
  v8::CompileUnbound(isolate, source, kConsumeParserCache);
