hevc: Add coefficient limiting to speed up IDCT
Noop again as we have these changes already, only random spacing
changes.

hevcdsp_template: Templatize IDCT
This commit is a noop as we already have that code from a previous
commits (see 92cccb7bcd).
Spacing is adjusted to reduce the diff.

hevc: Separate adding residual to prediction from IDCT
This commit should be a noop but isn't because of the following renames:
- transform_add → add_residual
- transform_skip → dequant
- idct_4x4_luma → transform_4x4_luma

As with sao_band_filter, pass instead the two variables from the struct needed in the function.
This simplifies writing asm optimized versions.

The x86 asm expects int32_t so use that type.
