First cut at bug 992 Fixes JS portion of DefineOwnProperty when there is an existing property and the new descriptor is generic. Makes code follow spec steps more closely. Fixes typo for check for unchanged enumerable in step 6. Adds regression test.

The the call of the builtin in InstanceofStub was not correctly protected with an internal frame leading to the return address being handled as a pointer during GC. Marked the Instanceof stub as allowing stub calls (the RecordWriteStub was removed some days ago). This issue was not caught by the assertion designed for this when debug mode is run with --debug-code (which out tests always does) as generating code for Abort set the allow stub calls flag to true. This has been fixed by restoring the allow stub calls flag correctly.

1. Added gdb style debugger commands (and their shortcuts) for d8. These include: - s[tep] : step into the current statement. - s[tep]i[n]: step into the current statement with the minimum step. - n[ext] : step to the next statement. - fin[ish] : step out of the current function. - cond : setting conditions on breakpoints. - d[elete] : deletes breakpoints. - en[able]|dis[able]: enables/disables breakpoints including exception breakpoints. - ignore : ignores a breakpoint for a specified period. - inf[o] ar[gs] : info on arguments of the current function. - inf[o] lo[cals] : info on local vars of the current function. - inf[o] br[eakpoints] : info on breakpoints. - l[ist] : similar to source, but allows the user to continually dump subsequent lines of source code either in the forward or backward direction. - quit / exit / disconnect : terminates the remote debugger session. NOTE: Active breakpoints will automatically be disabled when the remote debugger detaches. This allows v8 to continue to run without worrying about a loss of a debugger session. 2. Added support for breaking the debugger by simply typing ENTER. The break command is now optional. 3. Once the debugger is broken, the user can now just type ENTER to repeat the last command. This is useful to functionality that needs to be invoked repeatedly e.g. step, list. 4. Added more verbose descriptions in d8's help. 5. Fixed a line and column number offset bug in the listing of breakpoint line and column numbers. 6. Added a gc command to allow GCs to be requested from the debugger interface. The plumbing for requesting different types of GCs is there, but the underlying implementation currently only triggers a full mark-compact GC. The command also returns the before and after sizes of the heap. 7. Added trace json, and flags commands that are not published in help. trace json is used for tracing the debugger packets send from and received by d8. flags is for setting v8 flags. These are useful for people debugging v8 itself, but not necessarily users of v8. 8. Added the ability to enable and disable break on all / uncaught exceptions in to d8. 9. Added a fix to prevent the Debugger Agent from being re-instantiated if one already exists. 10. Added the ability to filter results of the script command by matching text or numbers on the results. 11. Added v8 flags to enable/disable the sending of debugger BeforeCompile, AfterCompile, and ScriptCollected events. 12. Fixed some undefined value bugs that resulted in v8 or the debugger failing. 13. Added a few minor WEBOS__ customizations (analogous to ANDROID customizations).

Currently, the bind for the slow label is after the pushing of the args registers which renders the args pushing dead code because there is a Ret preceeding it. The comments also imply that the arg pushing should be part of the InvokeBuiltins tail call.

For polymorphic calls (also loads and stores) we construct a type switch graph that has a basic block merging all the variants. There is an environment simulation before the goto at the end of all the predecessor blocks. This simulation is used to define the environment on entry to the successor block, and captures the return value of the call. In effect contexts, this value should not be present in the environment. The fix is to use the AST context to decide whether to have this value in the join node's environment at all.
