Additional flags can be passed to the kernel compilation step via the
DART_VM_FLAGS environment variable, but there's no way to specify
additional flags to be passed to the gen_snapshot step. This CL changes
that by also passing the contents of the GEN_SNAPSHOT_FLAGS environment
variable to that step, so the tool can be invoked like:
DART_CONFIGURATION=ReleaseX64 \
GEN_SNAPSHOT_FLAGS="--redirect-isolate-log-to=tmp/graphs.log \
--print-flow-graph-optimized" \
pkg/vm/tool/precompiler2 ...
