testsuite: Fix regression on m32 by r12-6087 [PR103820]
r12-6087 will avoid move cold bb out of hot loop, while the original
intent of this testcase is to hoist divides out of loop and CSE them to
only one divide. So increase the loop count to turn the cold bb to hot
bb again. Then the 3 divides could be rewritten with same reciptmp.
Tested pass on Power-Linux {32,64}, x86 {64,32} and i686-linux.
gcc/testsuite/ChangeLog:
PR testsuite/103820
* gcc.dg/tree-ssa/recip-3.c: Adjust.
