really does need to be a vector type, because
TargetLowering::getOperationAction for SIGN_EXTEND_INREG uses that type,
and it needs to be able to distinguish between vectors and scalars.
Also, fix some more issues with legalization of vector casts.

when the default case is winnowed down to be infeasible. When all
cases were ruled out (and the analysis state for the default case
would be infeasible) we would still consider the default case
possible. This fixes PR 5969.

putting relocations into the constant pool - this isn't needed
for correctness and in the rare occasion it happens would pull
us out of fast isel for the block.
If fast-isel application startup time ever becomes an issue we
can add better support for these addresses instead of bailing.

not just the viable ones. This is reasonable because the most common use of
deleted functions is to exclude some implicit conversion during calls; users
therefore will want to figure out why some other options were excluded.
Started sorting overload results. Right now it just sorts by location in the
translation unit (after putting viable functions first), but we can do better than
that.
Changed bool OnlyViable parameter to PrintOverloadCandidates to an enum for better
self-documentation.

1. CMPXCHG8B and CMPXCHG16B did not specify implicit physical register defs and uses.
2. LCMPXCHG8B is loading 64 bit memory, not 32 bit.

suggestions follow recovery. Additionally, add a note to these
diagnostics which suggests a fix-it for changing the behavior to what
the user probably meant. Examples:
t.cpp:2:9: warning: & has lower precedence than ==; == will be evaluated first
[-Wparentheses]
if (i & j == k) {
^~~~~~~~
( )
t.cpp:2:9: note: place parentheses around the & expression to evaluate it first

Compare the dominance information calculated using a dominance tree walk to the
information calculated based on DFS numbers, if XDEBUG is enabled.

Remove a FIXME and unify code that was necessary to work around broken
updateDFSNumbers(). Before updateDFSNumbers() did not work correctly for post
dominators.
llvm-svn: 92968
The DFS number calculation for postdominators was broken. In the case of
multiple exits that form the post dominator root nodes, do not iterate over
all exits, but start from the virtual root node. Otherwise bbs, that are not
post dominated by any exit but by the virtual root node, will never be assigned
a DFS number.
