Making LLD PDB generation faster
...LD by mmap'ing them.
The lockless DenseHash I was talking about will be published in an upcoming
patch. As for reproducibility, this can be an issue on build systems. But on
local machines, we could explicitly state that we want non-deterministic
builds, through some cmd-line flag. If your 57sec for "Type Merging"
transforms into 5sec when non-deterministic, I think that's worth it.

Making LLD PDB generation faster
Leonardo, to answer to your questions, yes to all of them You can take a
look at this prototype/proposal: https://reviews.llvm.org/D55585
Overall, computing ghashes in parallel at link-time and merging Types with them
is less costly that the current approach to merging. The 35sec you’re seeing
for merging should go down to about 15sec. The patch doesn’t parallelize
(yet) the Type merging
