ART: Simplify And(TypeConversion<Int64>(x), Const32).
Reorder the And and TypeConversion as
TypeConversion<Int64>(And(x, Const32))
for 32-bit constant Const32.
For example, java.io.Bits.getLong(byte[] b, int off) yields
better generated code on 32-bit platforms for each of its
eight "b[off + .] & 0xFFL" sequences.
Also remove obsolete "doThrow" code that attempts to prevent
inlining; the $noinline$ tag is now honored by the compiler.
Test: Added tests to 458-checker-instruct-simplification.
Test: m test-art-host-gtest
Test: testrunner.py --host
