along with "[arm64] Fix i/d cache line size confusion typo" and "Fix a warning about inline asm source/destination mismatches..." which were building on it. This reverts the following commits: 8d7399f9 474e6a3d c3ff68b6 Reason for revert: We're getting a large number of crash reports from arm64 devices that are obviously related to cache flushing after code patching. Bisection results say that the problems started at revision c3ff68b6. Since I can't find a bug in that CL except for the typo that I've fixed in 474e6a3d (which made some of the crashes go away but not all of them), we have no choice but to revert the changes in order to get stability under control while we investigate.

Denver supports a coherent cache mechanism. There is no need to clean the D cache and invalidate I cache. MTS has to check the translation anytime there is an I cache invalidate and this time can be saved by making FlushICache a NOP. The patch improves Octane by roughly 3-4% on Denver.

Move all of the CPU detection logic to the CPU class, and make all other code use the CPU class for feature detection. This also fixes the ARM CPU feature detection logic, which was based on fragile string search in /proc/cpuinfo. Now we use ELF hwcaps if available, falling back to sane(!!) parsing of /proc/cpuinfo for CPU features. The ia32 and x64 code was also cleaned up to make it usable outside the assembler.
