PR15662: Optimized debug info produces out of order function
parameters
When a function is inlined we lazily construct the variables
representing the function's parameters. After that, we add any
remaining unused parameters.
If the function doesn't use all the parameters, or uses them out of
order, then the DWARF would produce them in that order, producing a
parameter order that doesn't match the source.
This fix causes us to always keep the arg variables at the start of
the variable list & in the original order from the source.

Add support for optimized (non-generic) atomic libcalls.
For integer types of sizes 1, 2, 4 and 8, libcompiler-rt (and libgcc)
provide atomic functions that pass parameters by value and return
results directly.
libgcc and libcompiler-rt only provide optimized libcalls for
__atomic_fetch_*, as generic libcalls on non-integer types would make
little sense. This means that we can finally make __atomic_fetch_*
work
on architectures for which we don't provide these operations as
builtins
(e.g. ARM).
This should fix the dreaded "cannot compile this atomic library call
yet" error that would pop up once every while.
This should make it possible for me to get C11 atomics working on all of
our platforms.

Initial support for the AMD amdfam10 chipsets has been available in the
gcc43 branch under GPLv2. AMD and some linux distributions (OpenSUSE) did
a backport of the amdfam10 support and made it available.
This is a revised subset of the support initially brought in in r236962
and later reverted. The collateral efects seem to have disappeared but
it is still recommended to set the CPUTYPE with caution.

The "automatic" login feature is described as follows:
The USER environment variable holds the name of the person telnetting in.
This is the username of the person on the client machine. The traditional
behaviour is to execute login(1) with this username first, meaning that
login(1) will prompt for the password only. If login fails, login(1) will
retry, but now prompt for the username before prompting for the password.
This feature got broken by how the environment got scrubbed. Before the
change in r69825 we removed variables that we deemed dangerous. Starting
with r69825 we only keep those variable we know to be safe.
The USER environment variable fell through the cracks. It suddenly got
scrubbed (i.e. removed from the environment) while still being checked
for. It also got explicitly removed from the environment to handle the
failed login case.
The fix is to obtain the value of the USER environment variable before
we scrub the environment and used the "cached" in subsequent checks.
This guarantees that the environment does not contain the USER variable
in the end, while still being able to implement "automatic" login.

LoopVectorize: getConsecutiveVector must respect signed arithmetic
We were passing an i32 to ConstantInt::get where an i64 was needed and we must
also pass the sign if we pass negatives numbers. The start index passed to
getConsecutiveVector must also be signed.

This should fix Firefox crashes some people have been reporting, when it

LoopVectorizer: Fix 15830. When scalarizing and unrolling stores make
sure that the order in which the elements are scalarized is the same
as the original order.
This fixes a miscompilation in FreeBSD's regex library.
This should fix lib/libc/regex/regcomp.c at -O3 with clang 3.3 r178860
on CPUs with SSE. Before this change, the vectorizer could incorrectly
rearrange the second loop in computejumps(), leading to possibly invalid
entries in the re_gets::charjump table.
The net result was that for example "sed s/@CC@/foo/" failed to work
correctly, leading to trouble with many configure scripts.
