PR target/116365: Add user-friendly arguments to --param aarch64-autovec-preference=N
The param aarch64-autovec-preference=N is a useful tool for testing
auto-vectorisation in GCC as it allows the user to force a particular
strategy. So far, N could be a numerical value between 0 and 4.
This patch replaces the numerical values by more user-friendly
names to distinguish the options.
The patch was bootstrapped and regtested on aarch64-linux-gnu, no regression.
Ok for mainline?
