Mathias Bynens 7915cf939e [elements] Rename Has*Elements and Is*ElementsKind methods
Commit 26c00f4a4c improved the names of
most FAST_* elements kinds in the enum. This patch updates the matching
Has*Elements and Is*ElementsKind method names accordingly.

- HasFastSmiElements => HasSmiElements
- IsFastSmiElementsKind => IsSmiElementsKind
- HasFastObjectElements => HasObjectElements
- IsFastObjectElementsKind => IsObjectElementsKind
- HasFastSmiOrObjectElements => HasSmiOrObjectElements
- IsFastSmiOrObjectElementsKind => IsSmiOrObjectElementsKind
- HasFastDoubleElements => HasDoubleElements
- IsFastDoubleElementsKind => IsDoubleElementsKind
- HasFastHoleyElements => HasHoleyElements
- IsFastHoleyElementsKind => IsHoleyElementsKind

Additionally, FastHoleyElementsUsage is renamed to HoleyElementsUsage.
