Shrink size of dwarf2_per_cu_data
I noticed some holes in struct dwarf2_per_cu_data. This patch
rearranges the type slightly, and shrinks the size of some fields.
This reduces it from 136 bytes to 112 bytes (on x86-64).
I also reduced the size of the DWARF "version" fields in a couple of
spots. It seemed needless to use a short to hold a value that ranges
from 2 to 5, and this also helped the goal of shrinking
dwarf2_per_cu_data.
