The generated code for interface stubs sometimes just messes
with a few of the args and then tail-calls to the target routine.
The args that aren't explicitly modified appear to not be used.
But they are used, by the thing we're tail calling.

The combination of https://golang.org/cl/23650 and
https://golang.org/cl/23675 did not work--they were tested separately
but not together.
The problem was that 23650 introduced deferred argument checking, and
the deferred function loses the type that 23675 started requiring. The
fix is to go back to using an empty interface type in a deferred
argument check.
No new test required--fixes broken build.

When cgo writes a _cgoCheckPointerN function to handle unsafe.Pointer,
use the function's argument type rather than interface{}. This permits

getAbbrs looks like it is checking each month looking for a change
in the time zone abbreviation, but starts in Dec of the previous year
and skips the month of February because of the overflow rules for
AddDate. Changing the day to 1 starts at Jan 1 and tries all months
in the current year. This isn't very important or likely to change
output as zones usually span several months. Discovered when
looking into time.AddDate behavior when adding months.

Before, the Android exec wrapper expected the trailing exit code
output on its own line, like this:
PASS
exitcode=0
However, some tests can sometimes squeeze in some output after
the test harness outputs "PASS" and the newline. The
TestWriteHeapDumpFinalizers test is particularly prone to this,
since its finalizers println to standard out. When it happens, the
output looks like this:
PASS
finalizedexitcode=0
Two recent failures caused by this race:
https://build.golang.org/log/185605e1b936142c22350eef22d20e982be53c29https://build.golang.org/log/e61cf6a050551d10360bd90be3c5f58c3eb07605
Since the "exitcode=" string is always echoed after the test output,
the fix is simple: instead of looking for the last newline in the
output, look for the last exitcode string instead.

1) Calls to morestack were not processed to be PIC safe (must have been

2) jmpdefer needs to rewind the return address of the deferred function past
the instructions that load the GOT pointer into BX, not just past the call

That function call in turn overwrites the Go stack.
Fix that by fetching the global variable address once before the
stack register manipulation.
