`AST_Label.references` get `.initialize()` to `[]` every time after `.clone()`
So walk down the tree to pick up the cloned `AST_LoopControl` pieces and put it back together.
It's now available during tree walking, i.e. walker.has_directive("use
asm"), rather than as part of the scope. It's thus no longer necessary
to call `figure_out_scope` before codegen. Added special bits in the
code generator to overcome the fact that it doesn't inherit from
TreeWalker.
Fix#861
`-q 0` (default) use single or double quotes such as to minimize the number of
bytes (prefers double quotes when both will do); this is the previous
behavior.
`-q 1` -- always use single quotes
`-q 2` -- always use double quotes
`-q 3` or just `-q` -- always use the original quotes.
Related codegen option: `quote_style`.

Some `yargs` guru please tell me why `uglifyjs --help` doesn't display the
help string for `-q` / `--quotes`, and why it doesn't output the expected
argument types anymore, like good old `optimist` did.
The "key" property was always "set" or "get", which didn't make much sense.
Now it'll be the actual name of the setter/getter (AST_Node), and the
AST_Accessor object itself, which represents the function, won't store any
name.
Close#319
1b6bcca7 was a first attempt at this. That commit made Uglify stop replacing
holes with undefined, but instead it started replacing undefined with
holes. This is slightly problematic, because there is a difference between a
hole and an undefined value. More problematically, it changed [1,undefined] to
[1,] which generally doesn't even parse as a hole (just as a trailing comma), so
it didn't even preserve the length of the array!
Instead, parse holes as their own special AST node which prints invisibly.
AST_Accessor will represent the function for a setter or getter. Since they
are not mangleable, and they should not introduce a name in scope, we have a
new node for their name (AST_SymbolAccessor) which doesn't inherit from
AST_SymbolDeclaration.
fix#37
- use MAP.splice instead of a BlockStatement to inject code (avoids some
warnings in the linter)
- use the original symbol in exports, so that we get the proper source mapping
- a = a + x ==> a+=x
- joining consecutive var statements (hoisting is not always desirable)
- x == false ==> x == 0, x != true ==> x != 1
- x, x ==> x; x = exp(), x ==> x = exp()
- discarding useless break-s
- all symbols now have a `thedef` property which is a SymbolDef object,
instead of the `uniq` that we had before (pointing to the first occurrence
of the name as declaration).
- for undeclared symbols we still create a SymbolDef object in the toplevel
scope but mark it "undeclared"
- we can now call figure_out_scope after squeezing, which is useful in order
not to mangle names that were dropped by the squeezer
The following nodes were instances of AST_BlockStatement: AST_Scope,
AST_SwitchBlock, AST_SwitchBranch. Also, AST_Try, AST_Catch, AST_Finally
were having a body instanceof AST_BlockStatement.
Overloading the meaning of AST_BlockStatement this way turned out to be a
mess; we now have an AST_Block class that is the base class for things
having a block of statements (might or might not be bracketed). The
`this.body` of AST_Scope, AST_Try, AST_Catch, AST_Finally is now an array of
statements (as they inherit from AST_Block).
Avoiding calling superclass's _walk function in walkers (turns out we walked
a node multiple times).
if (foo) {
with (bar)
if (baz)
x();
} else y();
(the compressor removes the brackets since the consequent consists of a
single statement, but the codegen must include the brackets because
otherwise the `else` would refer to the inner `if`)
- added walker for AST_ObjectProperty
- handle redefinitions properly (only mangle one symbol, make them all point
to a single definition)
DynarchLIB seems to run fine after mangling + compressed output.
