Symbol allSymbols asBag occurrencesOf: #a
allSymbols returns an array of all symbols. The reason it contains #a twice:
There is OneCharacterSymbols.
- it is initialized with:
OneCharacterSymbols := (1 to: 256) collect: [ :i | (i - 1) asCharacter
asSymbol].
the #asSymbol puts the OneCharacterSymbols in the main symbol table already.
Then OneCharacterSymbols is just used by #allSymbols and #selectorsContaining:,
with the latter having no users.

Besides the bugfix, it removes some one Character symbols that never got used
and speeds up #allSymbols a little.
And it simplifies the code related to the symbol table a little, which will
make it easier to improve it later.
