The Dwarf2 information for Altvec vectors gave _unknown_ as a base type for the
vector instead of, in this case, 'short'.

Using the depricated 'attribute' scheme works, but the 'new' __vector does not,
so it could be considered a regression. 

This works correctly in 4.0.0

Here is an exmple of the bad dwarf:

     DW_AT_stmt_list   : 341
     DW_AT_high_pc     : 0x10000b08 268438280

I'm testing the backport of a fix for this.
