-      Loads the effective address of the position buffer (in a position shader)
-      or the varying buffer (in a varying shader). That is, the base pointer
-      plus the vertex's linear ID (the first source) times the buffer's
-      per-vertex stride. `LEA_VARY` should be executed once in a
-      position/varying shader, with the linear ID preloaded as `r59`. Each
-      position/varying store can then be constructed as `STORE` with the base
-      address sourced from the 64-bit destination of `LEA_VARY` and an
-      appropriately computed offset. Varying stores bypass the usual conversion
-      hardware for attributes; this diverges from earlier Mali hardware.
+      Load effective address of a buffer with an immediate offset added.
