gcc.dg/tree-ssa/slsr-8.c does "(int) index * (size_t) element_size",
which on LP64 targets can use a widening multiplication. Of course,
for simple element sizes like these, we end up using a shift instead,
but that's a decision that's rightly made later.
Tested on x86_64-linux-gnu, mips64-linux-gnu and mipsisa64-elf.
OK to install?
