RFR: 8267625: AARCH64: typo in LIR_Assembler::emit_profile_type

[Nick Gasson]

This code is generated when C1 is profiling types but it is known statically that there should only be one possible class at this point. It's supposed to then store the klass pointer into the method data when the expected class is actually observed but currently it does a load instead of a store.

I've attached a simple example to the JBS entry that shows the correct method data after changing LDR to STR. Also tested tier1 on AArch64.
