42552808ab Rename "global context" to "native context", 
in anticipation of the upcoming lexical global scope.

Mostly automatised as:

for FILE in `egrep -ril "global[ _]?context" src test/cctest`
do
  echo $FILE
  sed "s/Global context/Native context/g" <$FILE >$FILE.0
  sed "s/global context/native context/g" <$FILE.0 >$FILE.1
  sed "s/global_context/native_context/g" <$FILE.1 >$FILE.2
  sed "s/GLOBAL_CONTEXT/NATIVE_CONTEXT/g" <$FILE.2 >$FILE.3
  sed "s/GlobalContext/NativeContext/g" <$FILE.3 >$FILE
  rm $FILE.[0-9]

1d0f872ef9 Fix full code generator to not use --debug-code if it is in 
mksnapshot or a VM that is booted from a snapshot.  --debug-code
can still have an effect on stub and optimized code and it still
works on the full code generator when running without snapshots.

The deoptimizer generates full-code-generator code and relies on it having
the same layout as last time.  This means that the code the full code
generator makes for the snapshot should be the same as the code it makes
later.  This change makes the full code generator create more consistent
code between mksnapshot time and run time.

This is a bug fix and a step towards making the snapshot code more robust.

458e87fd05 Snapshots: Add --extra-code flag to mksnapshot which lets you specify a file 
with more JS code that is loaded into the VM before writing the snapshot.  Get
rid of the hard coded limit on the partial snapshot cache size.  This change
disables most of the serializer tests for the snapshot build of the VM: It's
getting too complicated to support both booting from a snapshot and then
creating a new snapshot from the same VM or loading more code with another
snapshot in the same VM.
