This will largely depend on the company - its size, its domain, and it will also depend on one's position within the company.
For example, the same senior C/C++/Java dev can have recurrent annual 10% raises in a larger enterprise or government outlet. He may also get irregular 20-30% performance based raises that sometimes double as retainers. While more likely to happen in a small companies, I saw it happen in larger (500+) companies too. Alternatively, he may get a year-end or a project-end bonus.
finally, he can also get no increase, which is the kind of bonus favoured by the game development sweatshops.
No wonder there's no unified stats on this. How can there be.
No only the position.
Having worked in two multi-nationals, they generally have a band or grade system. For the given band there's a min, max and midpoint. But, this is broken down by country, and in the USA often broken down by Bay Area, NYC, rest of country.
And like the other comments, at these places annual bonuses, project bonuses, and spot bonuses are usually budgeted for. If you don't hear about them, and you're in a big co. ask your manager, and if they don't know then you've got the wrong manager!
Someone in an HR role would have familiarity with this.
Also, glassdoor would be able to provide stats on this for decently large companies if they implemented this. I'm just a little hesitant to trust their numbers as is since some tech companies have obviously been around for a while...
