Proposed patch

Here is a patch that fixes these problems, as well as some other problems
related to numeric conversions. It fixes all of the JS Core tests related to
numeric conversion except three in ecma/TypeConversion/9.3.1-3.js. The first
two are actually incorrect tests:

--> - "-0x123456789abcde8" = NaN FAILED! expected: 81985529216486880
--> - "-0x123456789abcde8" = NaN FAILED! expected: 81985529216486880

The ECMA spec (9.3.1) does not allow signs in hexadecimal numbers coerced by
ToNumber(). The last is a specific instance of bug 4885:

--> -"\u20001234\u2001" = NaN FAILED! expected: -1234

It is difficult to make all of the conversion happen in one place, due to
different char sizes and slightly different parsing requirements. Maybe I will
do it at a later time when everything is using wide chars.
