Bug 515233: Move the TSF_DESTRUCTURING flag to the tree context. r=igor
...
The flag TSF_DESTRUCTURING is used by the parser to modify the way
variables in the destructuring pattern get represented in the parse
tree. It is never set or used by the tokenizer. This patch moves it
to JSTreeContext::flags, where it belongs, now that that field is wide
enough to hold it.
It also renames the flag TCF_DECL_DESTRUCTURING, since the flag is
only used for destructuring patterns that occur in declarations; it is
not set when processing assignment-like destructuring patterns.

Bug 515233: Widen JSTreeContext::flags to 32 bits. r=igor
...
All the bits in this uint16 field are currently in use. Adding bits
for projects like strict mode entails relocating existing flags, which
is additional work. Furthermore, it seems that this has already
inspired people to put flags in places they don't belong:
TSF_DESTRUCTURING is a JSTokenStream flag, but is only used by the
parser.
This patch widens the field to 32 bits, and adjusts JSFunctionBox and
a few other places to match.
We should really replace these all with bitfields.

Bug 515233: Make the static level its own parameter to JSCompiler::compileScript. r=igor
...
Pre-patch, the initial static level at which a script should be
compiled to run is passed in the upper sixteen bits of the tcflags
parameter to JSCompiler::compileScript; because JSTreeContext::tcflags
is a uint16, while the tcflags parameter is a uint32, we know the
parameter's upper bits are free.
However, we would like to enlarge JSTreeContext::tcflags to 32 bits,
as we already have a handful of new flags that belong there. This
patch moves the static level to its own parameter, which has a default
argument.

Bug 391488: Eliminate PTRDIFF macro; delete jssttddef.h. r=jimb
...
Delete jsstddef.h, since its only remaining purpose is to make certain
Win16-specific definitions; we don't support Win16 any more. In
particular, we can just subtract pointers now, so the PTRDIFF macro is
unnecessary noise.
Most places get stddef.h via jstypes.h or some other header, so we can
just delete #inclusions of jstddef.h. The exception is jskwgen.h, so
there we explicitly include <stddef.h> instead.
