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

The regexp flag should be correctly referenced and released
if an existing regexp like object is used for constructing a new one.

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

In ES2015 many builtin prototypes are no longer valid instances of their
respective classes. This change updates affected prototypes to be
regular objects as required.

Changes:
- Use the pre-scanner to provide information for the parser about the existence of the class constructor
- The allocation of the super declarative environment is no longer needed
- The VM frame context holds the information about the this binding status
- Reduce the number of class related VM/CBC instructions
- Improve ecma_op_function_{construct, call} to properly set new.target

First step to fix issue #3568.
Changes:
- Implemented Math.clz32(), Math.fround(), Math.imul(), Math.hypot().
- Implemented all remaining Math functions with calling the standard
libm functions, but they throw UNIMPLEMENTED exception with jerry-libm,
because the necessary fdlibm functions are missing and should be ported.
All Math related test262 tests pass (except function name and length tests)
