Teagan Strickland f822dfa3ea Reland "[vm/compiler] Implement new inlining pragmas."
This change introduces two new pragmas:

* `@pragma('vm:never-inline')`
* `@pragma('vm:prefer-inline')`

These replaces the old way of specifying AlwaysInline or NeverInline
annotations when the (now removed) --enable-inlining-annotations flag
was used.
