If visiting RHS causes us to finish 'Block', e.g. the RHS is a StmtExpr
...
containing a DoStmt, and the LHS doesn't create a new block, then we should
return RBlock. Otherwise we'll incorrectly return NULL.
Also relax an assertion in VisitWhileStmt(). Reset 'Block' when it is finished.

Tweaks to X86 instructions to allow the 'w' suffix in places it makes
...
sense, when the instruction takes the 16-bit ax register or m16 memory
location. These changes to llvm-mc matches what the darwin assembler
allows for these instructions. Done differently than in r117031 that
caused a valgrind error which was later reverted.

Clean up the API logging code:
...
- Try to reduce logging to one line per function call instead of tw
- Put all arguments & their values into log for calls
- Add 'this' parameter information to function call logging, making it show the appropriate
internal pointer (this.obj, this.sp, this.ap...)
- Clean up some return values
- Remove logging of constructors that construct empty objects
- Change '==>' to '=>' for showing result values...
- Fix various minor bugs
- Add some protected 'get' functions to help getting the internal pointers for the 'this' arguments...

Example:
bb0:

x = 2

When x is isolated in bb1, the inner part breaks into two components, x1 and x2:
bb0:

bb1:
x1 = x0
use(x1)

x2 = 2
x0 = x2
