      [array] Move Array.p.unshift fall-back to Torque · cfe71156
      Simon Zünd authored 
      This CL implements a generic baseline version of Array.p.unshift
in Torque, enabling us to remove the JS fall-back.

The elements-accessor fast-path is still used, but the check whether
to use it is also moved to Torque.

Support for sparse JSArrays is removed.

Drive-by change: Small refactoring in builtins-array that will
get extended to other array builtins in a follow-up CL.

      Simplify the processing of deferred code in the code generator. Our · bd82b972
      kmillikin@chromium.org authored 
      deferred code snippets are highly stylized.  They always make a call
to a stub or the runtime and then return.  This change takes advantage
of that.

Creating a deferred code object now captures a snapshot of the
registers in the virtual frame.  The registers are automatically saved
on entry to the deferred code and restored on exit.

The clients of deferred code must ensure that there is no change to
the registers in the virtual frame (eg, by allocating which can cause
spilling) or to the stack pointer.  That is currently the case.

As a separate change, I will add either code to verify this constraint
or else code to forbid any frame effect.

The deferred code itself does not use the virtual frame or register
allocator (or even the code generator).  It is raw macro assembler
code.

      Included mjsunit JavaScript test suite and C++ unit tests. · c42f5829

      In the shell sample don't print the result of executing a script, only
evaluating expressions.

Fixed issue when building samples on Windows using a shared V8
library.  Added visibility option on Linux build which makes the
generated library 18% smaller.

Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.

Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.

Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.
