ba64f485c8 Fix parameter of io error helper function
`set_last_error_from_io_error` works with only the error kind, and
discards the payload. Fix its signature to make it explicit.

892f706ce5 Add a support to execute isolated op without halting
In user interface, added a new flag `-Zmiri-isolation-error` which
takes one of the four values -- hide, warn, warn-nobacktrace, and
abort. This option can be used to configure Miri to either abort or
return an error code upon executing isolated op. If not aborted, Miri
prints a warning, whose verbosity can be configured using this flag.

In implementation, added a new enum `IsolatedOp` to capture all the
settings related to ops requiring communication with the
host. Old `communicate` flag in both miri configs and machine
stats is replaced with a new helper function `communicate()` which
checks `isolated_op` internally.

Added a new helper function `reject_in_isolation` which can be called
by shims to reject ops according to the reject_with settings. Use miri
specific diagnostics function `report_msg` to print backtrace in the
warning. Update it to take an enum value instead of a bool, indicating
the level of diagnostics.

Updated shims related to current dir to use the new APIs. Added a new
test for current dir ops in isolation without halting machine.

1ae157bc9e Replace target.target with target
Rustc removed the target wrapper and exposed the target directly.

Result of running:

find . -type f -exec sed -i -e 's/target\.target\([)\.,;]\)/target\1/g' {} \;

Plus one manual edit of the rust-version file
