When lastIndexOf is executed the array length can change and in
case of fast arrays the length should be re-checked.

New method uses length of source to calculate raw string length.
Also bug with template literal was fixed. Template object should have
indexed properties enumerable.

if an existing regexp like object is used for constructing a new one.

Template literals already supports escaping backslash and backtick,
this commit enables escaping this in String.raw.
It also fixes invalid behaviour of String.raw when using

was incorrect as it was dereferenced a bit to early.

Fixes two bugs in the index calculations that affect the result
of the `String.startsWith` function:
- Fixes the implementation of ECMA-262 v6, 21.1.3.18, step 14:
"If searchLength+start is greater than len, return false".
- Fixes the return value of the helper function
`ecma_builtin_helper_string_find_index`. If it is called with a
starting search position, the returned index should be
not less than that.
These changes fix the following test cases in the test262 suite:
- built-ins/String/prototype/startsWith/return-true-if-searchstring-is-empty.js
- built-ins/String/prototype/startsWith/searchstring-found-with-position.js

During ecma_collection_append the underlying collection
was not increased in the required case. This triggered
a buffer overflow when processing the bound function's arguments
during call or during the Proxy ownKeys method.
