generator, mimicing the behavior of the optimizing compiler.

Initialization blocks can only contain (thus begin and end) with a
property assignment in toplevel code.

ab3e85eeb4 Initial implementation of top-level compilation of expressions in test 
context.  Test contexts are used for the left subexpressions of
short-circuited boolean operators.  The right subexpressions inherit
their expression context from the binary op expression.

Compilation of short-circuited operations in effect and test context
is straightforward:

effect(e0 || e1) =
 test(e0, L0, L1)
 L1: effect(e1)
 L0:

test(e0 || e1, L0, L1) =
 test(e0, L0, L2)
 L2: test(e1, L0, L1)

Because the value of the first subexpression may be needed as the
value of the whole expression in a value context, we introduce a
hybrid value/test contest (the value is needed if true, but not if
false).

value(e0 || e1) =
 value/test(e0, L0, L1)
 L1: value(e1)
 L0:

The compilation of value/test and test/value (introduced by boolean
AND) is:

value/test(e0 || e1, L0, L1) =
 value/test(e0, L0, L2)
 L2: value/test(e1, L0, L1)

test/value(e0 || e1, L0, L1) =
 test(e0, L0, L2)
 L2: test/value(e1, L0, L1)

Boolean AND is the dual.  The AST nodes themselves (not their parents)
are responsible for producing the proper result (effect, value, or
control flow) depending on their context.

o.x() and o[expr]()

other changes:
- Fix missing relocation info for StoreIC on global object.
- Generate only one common return sequence instead of always appending 
  "return <undefined>" at the end of each function: The first JS 
  return-statement will generate the common return sequence. All
  other return-statements will generate a unconditional branch to the common
  return sequence.

143b4b87b4 Support for property assignment in the fast compiler. 
The code for .result = (b.y = 99) where b is a global variable is:

  push [esi+0x17]
  mov ecx,0xf5c229ad          ;; object: 0xf5c229ad <String[1]: b>
  call LoadIC_Initialize
  nop
  mov [esp],eax
  mov eax,0xc6
  mov ecx,0xf5c25c41          ;; object: 0xf5c25c41 <String[1]: y>
  call StoreIC_Initialize
  nop
  mov [esp],eax
  pop [ebp+0xf4]

There is still some room for improvement in the generated code.

Other changes:
 - Replaced switch-statement in FastCodeGenerator::VisitProperty with DropAndMove(...)
 - Do not emit nop after IC calls on ARM.

9ad7a66f98 Rename the kinds of locations to be consistent with the (codegen) 
context of the expressions they label.  Introduce an "unintialized"
location to catch failure to assign any location at all.

Changed the object literal initialization on ARM to use a Store IC in
the same cases where it did on the other platforms.  This was required
because the location of the literal property name is given an
"unitialized" location.

6a83cb0ced In the toplevel compiler, shift the responsibility of assigning a 
location to an Expression AST node from the node's parent to the node
itself.

This allows an inherited code generation context from a parent node to
be passed arbitrarily far down the tree (eg, the subexpression of a
unary not is in the same context as the unary expression itself, the
then and else subexpressions of the ternary operator are in the same
context as the whole expression, and so forth).

We do not yet take advantage of this in the backend (eg, the right
subexpression of short-circuited OR is still compiled by using the
parent's destination location, rather than the subexpression's
itself).

492dc0643f Fix crbug/24815. Changes affect profiler "lazy" mode used for V8 in Chromium. 
- don't engage the processing thread of CPU profiling until the first time profiling is resumed, this saves us a thread allocation for the majority of users;
- don't log shared libraries addresses: this is useless for JS-only profiling, and also consumes time on startup.
