This is a followup to D103422. The DenseMapInfo implementations for
ArrayRef and StringRef are moved into the ArrayRef.h and StringRef.h
headers, which means that these two headers no longer need to be
included by DenseMapInfo.h.
This required adding a few additional includes, as many files were
relying on various things pulled in by ArrayRef.h.

MBFIWrapper keeps track of block frequencies of newly created blocks and
modified blocks, modified block frequencies should also impact block profile
count. This class doesn't provide interface getBlockProfileCount, users can only
use the underlying MBFI to query profile count, the underlying MBFI doesn't know
the modifications made in MBFIWrapper, so it either provides stale profile count
for modified block or simply crashes on new blocks.
So this patch add function getBlockProfileCount to class MBFIWrapper to handle
new blocks or modified blocks.

Summary:
To avoid header file circular dependency issues in passing updated MBFI (in
MBFIWrapper) to the interface of profile guided size optimizations.
A prep step for (and split off of) D73381.
