> Fixed (the testcase with aligned(1)).  The original is INVALID.

The testcase with aligned(1) cannot pass on strict-alignment targets, either
with or without vectorization.  On the SPARC:

(botcazou@nile) /nile.build/botcazou/gcc-head/sparc-sun-solaris2.8 $ ./pr48377
Bus Error (core dumped)

On IA-64:

(botcazou@merced) /nile.build/botcazou/gcc-head/ia64-linux-gnu $ ./pr48377
pr48377(1543): unaligned access to 0x6000000000001041, ip=0x4000000000000650
pr48377(1543): unaligned access to 0x6000000000001045, ip=0x4000000000000650

pr48377(1543): unaligned access to 0x600000000000104d, ip=0x4000000000000650

Please move it to gcc.target/i386 or something equivalent.
