e60d667111 Module: fix @embedFile of files containing zero bytes 
If an adapted string key with embedded nulls was put in a hash map with
`std.hash_map.StringIndexAdapter`, then an incorrect hash would be
entered for that entry such that it is possible that when looking for
the exact key that matches the prefix of the original key up to the
first null would sometimes match this entry due to hash collisions and
sometimes not if performed later after a grow + rehash, causing the same
key to exist with two different indices breaking every string equality
comparison ever, for example claiming that a container type doesn't
contain a field because the field name string in the struct and the
string representing the identifier to lookup might be equal strings but
have different string indices.  This could maybe be fixed by changing
`std.hash_map.StringIndexAdapter.hash` to only hash up to the first
null, therefore ensuring that the entry's hash is correct and that all
future lookups will be consistent, but I don't trust anything so instead
I assert that there are no embedded nulls.

e57f553c07 LLVM Builder: Rework MetadataString to not rely on String 
This fixes a problem where empty strings where not emitted as null.
This should also emit a smaller stringtab as all metadata strings were
emitted in both the strtab and in the strings block inside the metadata
block.

d995029844 add BufferedTee 
BufferedTee provides reader interface to the consumer. Data read by consumer
is also written to the output. Output is hold lookahead_size bytes behind
consumer. Allowing consumer to put back some bytes to be read again. On flush
all consumed bytes are flushed to the output.

      input   ->   tee   ->   consumer
                    |
                 output

input - underlying unbuffered reader
output - writer, receives data read by consumer
consumer - uses provided reader interface

If lookahead_size is zero output always has same bytes as consumer.
