7624465b61 [es6] Fixed POSSIBLY_EVAL_CALL tail calls handling in Full codegen.
This CL also enhances a "tail-call-megatest" which now tests product of the following cases:
1) tail caller is inlined/not-inlined
2) tail callee is inlined/not-inlined
3) tail caller has an arguments adaptor frame above or not
4) tail callee has an arguments adaptor frame above or not
5) tail callee is a sloppy/strict/possibly eval/bound/proxy function
6) tail calling via normal call/function.apply/function.call

c67b5096cd [turbofan] Fixing ES6 tail calls in Turbofan.
In case when F inlined normal call to G which tail calls H we should not write translation for G for the tail call site.
Otherwise we will see G in a stack trace inside H.

This CL also adds a "megatest" which tests product of the following cases:
1) tail caller is inlined/not-inlined
2) tail callee is inlined/not-inlined
3) tail caller has an arguments adaptor frame above or not
4) tail callee has an arguments adaptor frame above or not
5) tail callee is a normal/bound/proxy function

Note that tests for not yet supported cases are not run for now.
