log: Add locking to large logging blocks
Reuse the existing locking provided by stdio to keep in_asm, cpu,
op, op_opt, op_ind, and out_asm as contiguous blocks.

While it isn't possible to interleave e.g. in_asm or op_opt logs
because of the TB lock protecting all code generation, it is
possible to interleave cpu logs, or to interleave a cpu dump with
an out_asm dump.

For mingw32, we appear to have no viable solution for this.  The locking
functions are not properly exported from the system runtime library.
