8068053: AARCH64: C1 and C2 compilers

[Roland Westrelin]

Hi Andrew,

> http://cr.openjdk.java.net/~aph/aarch64-8068053-2/

Shouldn’t c1_FpuStackSim_aarch64.[ch]pp be empty like it is on sparc?
What's ad_encode.m4 for?

Typo:
831 // advance declaratuons for helper functions to convert register

in aarch64.ad

That looks good to me.

Roland.
