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.

Since it is (currently) only an enum, change it to an enum (for now).

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.

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.

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).

- 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.

String slices from RegExp replace results is now encoded in either one or two smis. Substrings are not used any more.

If the existing one smi encoding cannot hold the start/length information two smis are used the first having the negative length and the second having the start.

This is in preparation for removing string slices.
