de619ae5a6 Fix --mangle-props and --mangle-props=unquoted 
Fixes: #1247

Fix --mangle-props and --name-cache inconsistency.
AST_Dot and AST_Sub properties are now mangled by --mangle-props
without regard to being used in an assignment statement.

Note: if --mangle-props is used then *all* javascript files used must
be uglified with the same mangle options.

Fix the ignore_quoted=true mangle option, also known as
`--mangle-props=unquoted`.  If a given property is quoted anywhere
it will not be mangled in any quoted or non-quoted context.

3a7d53f3cf Move OctalEscapeSequence to read_escape_char 
This should simplify and improve implementation, make it easier to
implement template strings, and keep master a bit more in sync with
harmony.

Previous implementation wasn't broken, though the loop gave me the
impression it could read infinite numbers and annoyed me a bit. It was
also slightly unnecessary because the lookup involved only 3 characters.

Respect quote style in object literals 
The option added in fbbaa42ee5 wasn't
being respected inside object literals, so quoted property names would
still be stripped out with this option.

This is mostly a corner-case, but useful when the output is passed to
something like the Closure compiler, where quoted property names can be
used to prevent mangling.

c75f5a1fd8 Fix #597 
NaN and Infinity were replaced in the output generation, instead of
during compression. This could lead to results where `1/0` was inserted
without parens leading to invalid output.

The nodes are replaced in the compression step now, and the output
generation returns their regular names. This should not be a problem,
since they're already only constructed from the original name.
