From the LL-origin inefficiency audit (finding O3). File/line references are from commit 0229f8872c; re-locate them before working.

Per-packet allocation burst in decodeData; double lookup per field

Where: lltemplatemessagereader.cpp:552-680, 85-104; llmessagetemplate.cpp:46-51; llindexedvector.h:50.
Note: the _PREHASH_ "Fast" getters do not compare strings; they are interned-pointer map keys. The waste is the allocations.
Confirmed. M-L.

Verify the cost (profile or timer) before and after changing it.
