Always produce PIC code for AOT compilation.
Change sharpening to use PIC load kinds for AOT compilation
and add "Jit" to the direct addressing load kind names. Use
PIC code also for the Integer.valueOf() intrinsic codegen.
Remove all support for non-PIC linker patches.
The dex2oat --compile-pic option is retained for now but
ignored by the compiler.
Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing
Test: Pixel 2 XL boots.
Test: testrunner.py --target --optimizing
