430e80d670 optimize constant layout. This fixes encoding of 181.mcf (by ensuring 
integer structure idx's are emitted before constant expr geps) and shrinks
files slightly.  For example kc++ shrinks from 4326188 to 4240128 bytes.

c1d86cda8c the type field for a store is the type of the pointer, not the value. 
With this fix I can round trip treeaadd, only losing calling conv info.

e53603e4e2 read a few instructions, fix some bugs. This is enough to be able to round 
trip function bodies like this:

define <2 x i64> @foo(<2 x i64> %x, <2 x i64> %y) {
        %tmp4 = bitcast <2 x i64> %y to <8 x i16>               ; <<8 x i16>> [#uses=1]
        %tmp5 = bitcast <2 x i64> %x to <8 x i16>               ; <<8 x i16>> [#uses=1]
        %tmp = add <8 x i16> %tmp5, %tmp4               ; <<8 x i16>> [#uses=1]
        %tmp6 = bitcast <8 x i16> %tmp to <2 x i64>             ; <<2 x i64>> [#uses=1]
        ret <2 x i64> %tmp6

6694f60bec Switch the bitcode reader interface to take a MemoryBuffer instead of knowing 
anything about disk I/O itself.  This greatly simplifies its interface -
eliminating the need for the ReaderWrappers.cpp file.

This adds a new option to llvm-dis (-bitcode) which instructs it to read
the input file as bitcode.  Until/unless the bytecode reader is taught to
read from MemoryBuffer, there is no way to handle stdin reading without it.

I don't plan to switch the bytecode reader over, I'd rather delete it :),
so the option will stay around temporarily.
