[NewPM][BasicAA] Rename basicaa -> basic-aa, add alias

Summary:
BasicAA under the new pass manager is called "basic-aa", which fits more
with the other AA names which almost always contain a dash.

Keep an alias from basicaa -> basic-aa.

Will change all references of "basicaa" to "basic-aa", then remove the
alias.

Makes check-llvm failures under NPM go from 2307 to 1867.
