Use ARM TTI in "opt" to make up for missing LE32 TTI.
Since we deleted the rewrite of ARM -> LE32 in the
bitcode reader, opt is unable to look up a TTI to transform
switch(c) { case 1: x = <const1>; break; case 2: x = <const2>; break; ... }
into a lookup table to get x from c.
This causes a regression in pnacl-llc's size (which has
lots of switch statements).
Fake the target lookup in opt for now. Eventually we should
look into making target info for le32.
