Revision 6309 changed which functions were considered lazy.
That also means that there must be preparse data for now non-lazy functions.

is that the mozilla ones were caused by the safe-point table problem
and the deoptimization ones are fixed by adding support for mod and
div.

Let's see if the buildbot agrees.

This change includes support for safepointtables and adding deoptimization info (but not for deoptimizing).

Implemented crankshaft functions:
CallCode
GenerateSafepointTable
RegisterEnvironmentForDeoptimization
EmitGoto


This change allows us to compile very simple functions with crankshaft:
An empty function
A function returning a constant.
A function returning a parameter.

There is 6 disabled tests that require us to be able to deoptimize
which is currently not supported.

The result can be a register, a stack slot or a constant operand.

Right now it is only used for enviroment uses.

Always emit the constant pool as part of generating deferred code
(whether or not there actually is any deferred code) and ASSERT that
there is no pending relocation info while using db and dd to write
tables.

This change introduces the third template parameters for LIR instructions
to specify the number of temp-operands. This is one step towards
removing the instruction-summaries.

I also added hydrogen-accessors in more places and refactored
the LIR-branch instructions to have common super-classes to 
avoid code duplication.

Added MUST_USE_RESULT to the functions that record uses
and definitions so that all LOperands are stored in the
LIR instructions (and not only in the summaries).

Instead of spilling and then immediately restoring eax to resolve
memory to memory moves, the gap move resolver now tracks registers
that are known to be free and uses one if available.  If not it spills
but restores lazily when the spilled value is needed or at the end of
the algorithm.

Instead of using esi for resolving cycles and assuming it is free to
overwrite because it can be rematerialized, the gap move resolver now
resolves cycles using swaps, possibly using a free register as above.

The algorithm is also changed to be simpler: a recursive depth-first
traversal of the move dependence graph.  It uses a list of moves to be
performed (because it mutates the moves themselves), but does not use
any auxiliary structure other than the control stack.  It does not
build up a separate list of scheduled moves to be interpreted by the
code generate, but emits code on the fly.

When processing register contraints we used to add writable input operands
also as temp operands to the same instruction.

This does not seem necessary since we create a fresh virtual register
for writable inputs and insert a definition in the gap before the instruction.

Previously we delayed the throwing of syntax errors until runtime, so
unreachable errors didn't get reported.
To match a change in JSC, we now stop parsing and report the error immediately.

As invocation of a functin may trigger GC and hence clear all the caches,
it's hard to ensure previous invariants.

Current invariant is both a key and a value should be the holes or not holes.

This puts us very close to being able to compile the empty function.

This changes only has a small number of 64 bit specific assembler instructions.

The remaining changes are much more platform specific and will go in another change.
