Patch Function#call and Function#apply together, more robust than…

… single fix.

Ref: es-shims#304

Changed some code back as mentioned in comments.

Changed more code as per comments

Changed more code as per comments.

Changed some variable names to better reflect comments.

Fixed missed invocation.

Added some comments and code changes as discussed.

[tests] Remove unneeded jshint comment.

[Tests] use the preferred it/skip pattern for this strict mode test.

es-shims#345 (comment)
And some other cleanup

Added `arguments` expectations to tests.

Add tests for `Object#toString` of typed arrays and Symbols, if they exist.

Added note about typed array tests.

Fix `hasToStringTagRegExpBug`

Removed RegExp and Array bug detection as can not test, possible Opera 9.
Fixed missing `force` on `defineProperties` that caused the patch to not be applied on IE<9.
Fixed `Uint8ClampedArray` tests for Opera 11 and IE10 that don't have it.

Removed offending test that was moved to detection, but forgotten.

Avoid all possibilities of `call` calling `call`.

Do not pass `undefined` argument, we know IE<9 has unfixable bug.

Final cleanup (hopeully)

Port over work from `apply` fix

Move code so that it is specific to the fix.

Robustness, move before bind.

Remove `Array#slice` tests.

Add notes about `eval` and `apply` avoidance.
