Summary: See D753. Let's just have lint fix this. Depends on D754 (it fails to
detect all the blocks without that patch, but doesn't do anything bad).
Test Plan: Ran unit tests.

Summary:
cpojer fixed a JS instance of this in D481, but we can catch it in PHP with
XHPAST. Add a lint rule to fail if nested loops use the same iterator.
Test Plan:
Ran unit test.

Summary:
This is pretty coarse and could be refined, but I often do this when testing:
lang=diff
- if (some_complicated_condition())
+ if (true || some_complicated_condition())
aran has caught me not only doing it but sending out diffs with it like 30
times. Catch it in lint instead.
Test Plan:
Unit test, added a "true || $junk" to the code and linted it.

Summary:
Raise an error if an array is initialized with the same key present more than
once.
Test Plan:
bin/arc unit
Also added some duplicates to ArcanistXHPASTLinter.php and verified the output
of bin/arc lint.

Summary:
This isn't necessarily a root-cause solution but this syntax is really really
bad. If we want to fix the root cause, I'd recommend making its use a lint
error?
Test Plan:
Unit tests failed before patch, passed afterward.

Summary:
XHPAST encounters a parse-depth problem on some files because PHP
5.2 has an un-overridable parse depth limit for JSON. The text of this error
says it is a "warning" but we currently raise an error. Make it a warning
instead.
The JSON depth is 20 until PHP 5.2.3, where it becomes 128. After PHP 5.3
it defaults to 512 and is user-configurable, which will allow us to resolve
this issue in nearly all cases.
Since I made if/else express as a list in the AST, this only actually arises
in long binary chains, most commonly string concatenation, like:
$out = 'a'.'a'.'a'.'a'...
...where each string is a variable or HTML tag and the program is constructing
a complicated document.
At some point I'll add some PHP 5.3 massaging to the XHPAST decoder itself to
raise this limit to something more huge.
Test Plan:
Ran "arc lint --lintall" on a file with a very deep binary
expression tree ("1 + 1 + 1 ...") and received a warning instead of an error.
