RFR: AArch64: 8209415: Fix JVMTI test failure HS202

[Andrew Haley]

In a moment of madness one of us (no names, no pack drill!)  managed
to translate from x86

    __ cmpb(Address(rbcp, 0), Bytecodes::_invokestatic);
    __ jcc(Assembler::notEqual, L_done);

to

    __ ldrb(rscratch1, Address(rbcp, 0));
    __ cmpw(r1, Bytecodes::_invokestatic);
    __ br(Assembler::EQ, L_done);

Two bugs in thee lines... fixed thusly.

OK for trunk and jdk8u ?
