Matthew Dempsky 9371a65584 internal/pkgbits: change EnableSync into a dynamic knob
Rather than requiring users to recompile the compiler and all tools to
enable/disable sync markers, this CL adds a flag word into the Unified
IR file format to allow indicating whether they're enabled or not.
This in turn requires bumping the file format version.

Thanks to drchase@ for benchmarks showing this isn't as expensive as I
feared it would be.

Matthew Dempsky 4e4db1e257 internal/pkgbits: add Index type
Element indices are very common in the pkgbits API, so introduce a new
defined type to help make that clearer.

Matthew Dempsky 42ca44494c internal/pkgbits: add fingerprints to unified IR export format
So far unified IR has been relying on the backwards-compat iexport
data to supply package fingerprints for imports. To be able to drop
the iexport data and natively use unified IR everywhere.

This CL applies basically the same idea that iexport used: simply
hash all of the export data as it's being written out, and then tack
on an 8-byte hash at the end.

Matthew Dempsky d40e7bb174 internal/pkgbits: add version number
Especially once this code gets copied into x/tools, we need a way to
evolve the file format, so add an explicit version number.

Matthew Dempsky 7c151f3280 internal/pkgbits: extract unified IR coding-level logic
This logic is needed for the go/types unified IR importer, so extract
it into a separate internal package so we can reuse a single copy.
