Fixes to run "Hello, world!" on arm64 hardware.
...
Primarily, in Dart code, instead of using R31 as our
stack pointer, on entry we copy it into a second
register (R18) and use that as our stack pointer after
moving R31 to the Dart stack limit. On calling back
into C++ from Dart code, R31 is restored, and R18 is
cached in the callee-saved register R26.

Adds support for ARMv6.
...
When we detect ARMv6, instead of using movw and
movt, this change loads each individual byte.
Although this is not the best way to achieve this,
a modification to store large constants in the
object pool would be more invasive. Further,
this change will be easier to back-out once
ARMv6 is obsolete.

Refactors some CPU feature detection into new class CpuInfo, and uses new information in VM service.
...
This change rewrites the code from the ARM assembler for parsing /proc/cpuinfo on Linux and Android, and collects it into a CpuInfo class that can be used for other architectures as well. This code is in cpuinfo_*.cc. /proc/cpuinfo equivalents are used for Mac and Windows. CpuInfo is used by the VM service to report on the hardware dart is running on. In the future CpuInfo can also be used here to provide more information.
