Zachary Turner ce5491291a [pdb] Change /DEBUG:GHASH to emit 8 byte hashes. ...

Previously we emitted 20-byte SHA1 hashes.  This is overkill
for identifying debug info records, and has the negative side
effect of making object files bigger and links slower.  By
using only the last 8 bytes of a SHA1, we get smaller object
files and ~10% faster links.

This modifies the format of the .debug$H section by adding a new
value for the hash algorithm field, so that the linker will still
work when its object files have an old format.
