Long precompilation times

[mwallerb]

SparseIR is now super-fast to load. However, it does take quite long to precompile.

I don't understand why this should be, since we mostly do bog-standard linear algebra ... or is the quad-precision linear algebra just much slower?

Quite a small issue, but it is a little annoying :)

On my Macbook Pro M1

julia> @time Base.compilecache(Base.identify_package("SparseIR"))
[ Info: Precompiling SparseIR [4fe2279e-80f0-4adb-8463-ee114ff56b7d]
 20.228946 seconds (3.60 k allocations: 326.414 KiB)

Yes, it is a bit long, although I was not aware of this issue.

Disabling quad-precision (i.e. replacing Float64x2 by Float64) reduces precompilation from ~45 to ~30 seconds on my laptop. I have tried in the past to speed this up, but don't really have a clue how to diagnose where the time is spent.
