Dump instruction set features in .cfg
This commit adds a compilation block at the beginning of the .cfg
dumped by the optimizing compiler when --dump-cfg is enabled.
The compilation block appears in the following form:
begin_compilation
name "isa_features:feature1,-feature2"
method "isa_features:feature1,-feature2"
date 1580721972
end_compilation
This compilation block dump is passed to checker script (see
https://android-review.googlesource.com/c/platform/art/+/1290997)
for checking if a certain instruction set feature was used at compile
time.
