Martin Kustermann 31dd6683f8 [VM] Optimize performance of dart_boostrap in debug-kernel-strong mode. 
Since the kernel reading helpers have been extended to not only work
with a kernel blob in C heap, but also work based on a [TypedData]
buffer in the VM heap, access to the [TypedData] buffer is on the hot
path now.

This hot path is slowing things down considerably, in particular due
to NoSafepoingScope's.

This CL removes a critical NoSafepoingScope when accessing the
[TypedData] in read-only mode.  It also allows passing in the [Thread]
directly, to avoid TLS lookups.
