Pls fix the compilation error

fix it c95e85f

Thanks for your patching.
I understand emplace is more efficient than insert because emplace reduces extra object copy, so you proposed this PR. One question for my curiosity, didn't you meet perf issues bottlenecked by the STL container operations? Or the PR is proposed out of motivations to make code better?

@MicroYY
It's more like code refactoring, optimization is insignificant, but there is, better pay ur attention to 2 previous PR where code generation is really optimized and media-driver can save time on pre-reserved memory.

reserve vector optimization insert: #1869

And there is also very good optimization classes and structures that are often moved and copied, optimization affects all modern x64 processors.

align for x64 cpu: #1873

@MicroYY maybe I split commit into many commits? Code review takes a long time.
