arm asm: Let .fpu enable instructions, PR20447.
I'm not very happy with duplicating the fpu->feature mapping in ARMAsmParser.cpp
and in clang's driver. See the bug for a patch that doesn't do that, and the
review thread [1] for why this duplication exists.

This makes the .fpu directive work properly, so we can successfully
assemble several .S files using the directive, under lib/libc/arm.
Allow CP10/CP11 operations on ARMv5/v6
Those registers are VFP/NEON and vector instructions should be used instead,
but old cores rely on those co-processors to enable VFP unwinding. This change
was prompted by the libc++abi's unwinding routine and is also present in many
legacy low-level bare-metal code that we ought to compile/assemble.
Fixing bug PR20025 and allowing PR20529 to proceed with a fix in libc++abi.
This enables assembling certain ARM instructions used in libgcc.
crowded as we now are at about 70k. Bump the limit to 1MB instead
which is still quite a reasonable limit and allows for future growth
of this file and possible future expansion to additional data.

recursion on mutex initialization.
The only places where the recursive acquire is performed are read and
write filters, since knlist, which uses the pipe pair mutex as lock,
is locked when filter is called.
The recursion was added in r93296, and consistent locking for
kn_fop->f_event() introduced in r133741.

that needs it and is always done: make.conf build.
(*) In our build environment we actually never do a clean build unless
instructed to do so, to make sure we do not accidentally delete the
built world when on a tight schedule.
As a side effect...
1. The tests now checks for the root user before continuing with kyua, which is
more visible than the test being skipped with the TAP protocol
2. The tests work with devices that aren't /dev/md0 by caching the device
attached during the test to a file, and later use the cached information to
detach the device in the cleanup routine
3. The tests no longer require perl to run

Revert "Added inst combine transforms for single bit tests from Chris's note"
This reverts commit r210006, it miscompiled libapr which is used in who
knows how many projects.
A test has been added to ensure that we don't regress again.
This fixes a miscompilation in libapr, which caused problems in svnlite.
