some alpha benchmarks

[Alexander V. Lukyanov]

Recently I tried different version of egcs and gcc on alpha ev5.

All compilers were given -O9.

gcc-2.7.2.3	1217431.250000 dhrystones/second
gcc-2.8.0	1203512.375000 dhrystones/second
egcs-1.0.1	1180675.500000 dhrystones/second
egcs-1.0.1haifa	1227936.500000 dhrystones/second
egcs-980122haifa 804820.500000 dhrystones/second

Strange, the newest snapshot is much slower...
