delete a node even if it was not dead in some cases.  Instead, just add it to
the worklist.  Also, make sure to use the CombineTo methods, as it was doing
things that were unsafe: the top level combine loop could touch dangling memory.

This fixes CodeGen/Generic/2008-01-25-dag-combine-mul.ll

don't bother making x&-1 only to simplify it in dag combine.  This commonly occurs expanding i64 ops.

Added back logic in patch r46361 (http://llvm.org/viewvc/llvm-project?rev=46361&view=rev) with the addition of
some previously missing NULL pointer checks.

Modified the UninitializedValues analysis to not expect that every Expr* at the
block-level is a block-level expression (we probably need to change the name of
such expressions to something truer to their meaning).

Renamed RValueConjunctiveUnequal to RValInequalityANDSet.

Refactored add/subtract/multiple (and now divide) operations for
RValEqualityORSet to be based on a single template function.

was actually passing a completely incorrect size to sys_icache_invalidate.
Instead of having the JITEmitter do this (which doesn't have the correct 
size), just make the target sync its own stubs.

return false, if someone calls isTruncStoreLegal
or isLoadXLegal with an extended type for the in
memory type.

DeadStoreElimination can treat byval parameters as if there were alloca's for the purpose of removing end-of-function stores.

we can infer it.  This will eventually help stuff, though it doesn't
do much right now because all fixed FI's have an alignment of 1.

Replace Sema::CheckVariableInitList, CheckConstantInitList, and CheckForCharArrayInitializer with CheckInitializerListTypes. The new routine now supports struct/union initializers.

This is a modified version of a patch by Eli Friedman. This version passes all of the clang tests and supports vectors:-)

Note that Eli and I are still unsatisfied the implementation of CheckInitializerListTypes(). We'd like to find a more elegant implementation. Nevertheless, this is a complex part of the standard (and may be hard to simplify). Since the complexity is localized to this routine, we can iterate without too much disruption:-)
