6bdc101c63 src,lib: retrieve parsed source map url from v8 
V8 already parses the source map magic comments. Currently, only scripts
and functions expose the parsed source map URLs. It is unnecessary to
parse the source map magic comments again when the parsed information is
available.

by the RegExp which caused sourcemaps not be loaded when using the

803a7b2b23 src,lib: print source map error source on demand 
The source context is not prepended to the value of the `stack` property
when the source map is not enabled. Rather than prepending the error
source context to the value of the `stack` property unconditionally,
this patch aligns the behavior and only prints the source context when
the error is not handled by userland (e.g. fatal errors).

Also, this patch fixes that when source-map support is enabled, the
error source context is not pointing to where the error was thrown.

0214b90308 process: fix two overflow cases in SourceMap VLQ decoding 
These both have to do with extremely large numbers, so it's unlikely to
cause a problem in practice. Still, correctness.

First, encoding `-2147483648` in VLQ returns the value `"B"`. When
decoding, we get the value `1` after reading the base64. We then check
if the first bit is set (it is) to see if we should negate it, then we
shift all bits right once. Now, `value` will be `0` and `negate` will
be `true`. So, we'd return `-0`. Which is a bug! `-0` isn't
`-2147483648`, and we've broken a round trip.

Second, encoding any number with the 31st bit set, we'd return the
opposite sign. Let's use `1073741824`. Encoding, we get `"ggggggC"`.
When decoding, we get the value `-2147483648` after reading the base64.
Notice, it's already negative (the 32nd bit is set, because the 31st was
set and we shifted everything left once). We'd then check the first bit
(it's not) and shift right. But we used `>>`, which does not shift the
sign bit. We actually wanted `>>>`, which will. Because of that bug, we
get back `-1073741824` instead of the positive `1073741824`. It's even
worse if the 32nd and 31st bits are set, `-1610612736` becomes
`536870912` after a round trip.

I recently fixed the same two bugs in Closure Compiler:
