Read the bitcode module and prepare for lazy deserialization of function bodies.
If ShouldLazyLoadMetadata is true, lazily load metadata as well. If IsImporting is true, this module is being parsed for ThinLTO importing into another module.

Returns the contents of a bitcode file.
This includes the raw contents of the symbol table embedded in the bitcode file. Clients which require a symbol table should prefer to use irsymtab::read instead of this function because it creates a reader for the irsymtab and handles upgrading bitcode files without a symbol table or with an old symbol table.
