ART: Generate path to entrypoints in VisitLoadString for arm

ARM32 boot.oat with CC: 72534816 -> 71888864 (-0.9%)

Move code that branches to entrypoints from GenerateSlowPaths to
VisitLoadString. Since we're doing this every time, we shouldn't have it
at the end with all of the slow paths.

Test: N6P booting with CC, test-art-target32 on shamu
