2eaf2a2e40 where possible, encode symtab names with 7 bits per char instead of 8. This
shaves 110K off kc++ to 3514K.  Before:

94c8c289d0 Encode all value symtab strings as arrays of 8-bit fixed width integers,
instead of the default inefficient encoding.  This shrinks kc++ from 4134K
to 3629K

I just introduced), stub out function reading, purge aggregate values from
the value table before reading functions.

b7c184cbc1 Initial support for writing bitcode files. This currently only writes types,
the type symtab, and global/function protos, and is missing the important
size optimization, but it is a place to start.
