02252a653d Bug 482743: Fix up bytecode execution tracing. Allow tracing to file. r=igor 
js_TraceOpcode: Remember the last bytecode we traced explicitly,
instead of subtracting 'len' from regs.pc, which isn't reliable.
Decline to trace values in script prologues (between 'code' and
'main').  Decline to walk off the bottom of the stack when the 'last
bytecode' is misleading.  Flush the stream after each bytecode.

Use the TRACE_OPCODE macro in both threaded and non-threaded
interpreters.  Take care to make threaded and non-threaded
interpreters produce the same traces.

In the shell's 'tracing' function, use JS_ValueToBoolean to recognize
all sorts of booleans, and treat a string as the name of a file to
write the trace to.

debdb32ef3 Bug 480132: Clone lexical blocks only when needed. r=igor 
Terminology:

A "script block" is an object of class Block allocated by the byte
compiler and associated with a script.  Script blocks are never
modified, and may be used as a prototype for a "closure block":

A "closure block" is an object of class Block that holds variables
that have been closed over (although we actually leave the variables
on the stack until we leave their dynamic scope).  A closure block is
a clone of a script block (its prototype is a script block).

Adjust the meanings of fp->blockChain and fp->scopeChain:

  fp->blockChain is always the innermost script block in whose static
  scope we're executing.

  fp->scopeChain is the current scope chain, including 'call' objects
  and closure blocks for those function calls and blocks in whose
  static scope we are currently executing, and 'with' objects for with
  statements; the chain is typically terminated by a global object.
  However, as an optimization, the young end of the chain omits block
  objects we have not yet needed to clone.

Closures need fully reified scope chains, so have js_GetScopeChain
reify any closure blocks missing from the young end of fp->scopeChain
by cloning script blocks as needed from fp->blockChain.  Thus, if we
never actually close over a particular block, we never place a closure
block for it on fp->scopeChain.

Have JSOP_ENTERBLOCK and JSOP_LEAVEBLOCK always keep fp->blockChain
current.  When JSOP_LEAVEBLOCK pops a block from fp->blockChain that
has been cloned on fp->scopeChain, pop fp->scopeChain as well.

Remove the JSFRAME_POP_BLOCKS flag, as it is no longer needed.

Ensure that the JIT won't have to create closure blocks or call
js_PutBlockObject; it can't handle those things yet.  Note our current
script block when we begin recording.  Abort recording if we leave
that block; we can't tell in advance whether it will need to be "put"
in future trace invocations.  Leave trace if we call js_GetScopeChain
while in the static scope of lexical blocks.  Remove JIT tests based
on JSFRAME_POP_BLOCKS.

Verify that generators capture the correct value for blockChain.

Add a constructor to JSAutoTempValueRooter for rooting JSObject
pointers.

90bf6a2d1e Bug 97954: Give jsconfig.h a better name, and make room for the new js-config.h. r=bsmedberg 
We'd like the SpiderMonkey configure script to generate a header file
named js-config.h to hold #definitions chosen at configure time that
affect the SpiderMonkey API, like JS_THREADSAFE.  However, that name
is very similar to that of an existing header file, jsconfig.h.  This
patch renames the existing header file, and updates all references to
it.
