This still happens after update and rebuild:

$ /home/ghost/build/llvm-gcc/install/bin/gcc -g -S -fno-inline -o test.llvm 
tests/2003-05-26-Shorts.c
$ gccas -disable-inlining test.llvm -o test.bc
$ llvm-dis -f test.bc
$ less test.ll
........
int %main(int %argc, sbyte** %argv) {
entry:
        call void %__main( )
        %tmp.11 = call ulong %getL( )           ; <ulong> [#uses=16]
        %tmp.3 = cast ulong %tmp.11 to long             ; <long> [#uses=
6]
        %tmp.5 = cast ulong %tmp.11 to uint             ; <uint> [#uses=
6]
        %tmp.7 = cast ulong %tmp.11 to int              ; <int> [#uses=7
]
        %tmp.9 = cast ulong %tmp.11 to ushort           ; <ushort> [#use
s=3]
        %tmp.11 = cast ulong %tmp.11 to short
