Fix encoding bug in js_dtoa_radix (#399)
- fix radix conversion rounding code: incrementing the digit
  does not work for '9'.  We can assume ASCII so it works for
  all other digits, especially all letters
- also avoid recomputing the string length

Accept /[\-]/u as a valid regular expression (#288)
The non-Unicode version of the pattern was already accepted.

test262 tests it in an inverted sense in
test/built-ins/RegExp/unicode_restricted_identity_escape.js but
it appears to be per spec and both V8 and Spidermonkey accept it.

Record source column positions (#193)
And:
- display them in stack traces
- expose them as Function.prototype.columnNumber

OP_line_num is renamed to OP_source_loc and the pc2line data structure
is extended with the column number in zigzag encoding.

The bytecode version number BC_VERSION is incremented because pc2line
data is read and written by JS_ReadObject() and JS_WriteObject() when
it is present.

Fix stack overflow in CVE-2023-31922 (#157)
isArray and proxy isArray can call each other indefinitely in a mutually
recursive loop.

Add a stack overflow check in the js_proxy_isArray function before calling
`JS_isArray(ctx, s->target)`.

bfd8c381cb Add support for building with ClangCL on Windows
Since ClangCL is compatible with MSVC this should get us almost there.
