9a58807030 [turbofan] Optimize add operations to use 'leal' instruction on x64 
Add MemoryOperandMatcher that recognizes node clusters in the form
[%r1 + %r2*SCALE + OFFSET] and explicit support in the x64 Int32Add
selector to use it to translate complex adds to 'leal' instructions.

744c66bc29 [turbofan] Introduce separate SelectLowering reducer. 
Split lowering of Select nodes into a separate graph reducer and be more
clever when lowering to diamonds, i.e. reuse diamonds that have the same
condition and only add more phis to it.

e3294b1f09 [turbofan] Fix lowering of typed loads/stores. 
Only JSLoadProperty/JSStoreProperty nodes with external typed arrays can
be lowered to LoadElement/StoreElement, because lowering of non-external
typed arrays would require a map check.

5899cc8ca7 [turbofan] Fix lowering of typed loads/stores. 
We can only access to external typed arrays; lowering of internal
typed arrays would require a map check plus eager deoptimization.
Also embed the array buffer reference directly instead of embedding
the typed array.

This reverts commit r22847 and r22848. Isolate initialization/shutdown
still broken (so certain debug builds just crash), and our compiler flags
do not work with other Google projects (i.e. GTest/GMock).
