Dynamic input type no longer works with v-model and :value at the same time.

Version

2.5.13

Reproduction link

https://codepen.io/anon/pen/KZyJyy

Steps to reproduce

Open JS console and see `[Vue warn]: Error compiling template:

{{ testitem }}

{{ testvalue }}

• :value="testitem" conflicts with v-model on the same element because the latter already expands to a value binding internally

(found in )`

What is expected?

Template compiled without errors, just like in Vue 2.5.3

What is actually happening?

Errors while template compilation. On codepen this still renders component, but webpack wont build bundle because of this error.

This code worked on 2.5.3, https://codepen.io/anon/pen/opomGr

This warning message was added in v2.5.5, so that you were not able to see it on v2.5.3.

Ok, what do we do about it? I want this dynamic input :type.

Actually I think the warning shouldn't be emitted here. For inputs with dynamic type binding, we may just skip the conflict check because the actual type is not available yet in the compiler.

I made a PR to resolve this issue: #7406.
