U74 asm kernel: note full-memory HPL result in header 

Full-memory HPL N=27456 (asm hybrid + Q=256) measured at 5.99 GFLOPS
(residual PASSED, ~50% of the 12 GF peak, +10.7% over the tuned C kernel,
1.81x the stock 2x2) - the best clean figure. Doc-only header update.

* double-buffering (P/Q ping-pong) and load-before-FMA issue ordering that
* reaches the U74 FP-pipe peak (~16.5 cycles per 16 fmadd.d). All other
* shapes, odd bk, and the TRMM builds fall back to the portable C 4x4 code

* 0 failures) and HPL (residual PASSED).
