(which is constant time and cheap) before checking hasAllZeroIndices.

4c25cb12ea Do not inline functions with (dynamic) alloca into 
functions that don't already have a (dynamic) alloca.
Dynamic allocas cause inefficient codegen and we shouldn't
propagate this (behavior follows gcc).  Two existing tests
assumed such inlining would be done; they are hacked by
adding an alloca in the caller, preserving the point of
the tests.

5a8a2b046d ValueTracker can't assume that an alloca with no specified alignment 
will get its preferred alignment.  It has to be careful and cautiously assume
it will just get the ABI alignment.  This prevents instcombine from rounding
up the alignment of a load/store without adjusting the alignment of the alloca.

71f808dfa2 * Don't explicitly cast "0" to "void*". This doesn't work well with specialized 
StringMapEntryInitializer classes. Leave it for the compiler to figure out what
 the type is and what "0" should be transformed into.

* Un-disable the unit tests which test the StringMapEntryInitializer class.

759c4201e9 the new scalarrepl changes are optimizing away a temporary alloca in 
check242, which invalidates this test.  This test is an x86-32 ABI test 
that is trying to be run in a target-independent way, which is not going
to work very well.  Just remove the test.

60a03a2f36 This implements the second half of the fix for PR3290, handling 
loads from allocas that cover the entire aggregate.  This handles
some memcpy/byval cases that are produced by llvm-gcc.  This triggers
a few times in kc++ (with std::pair<std::_Rb_tree_const_iterator
<kc::impl_abstract_phylum*>,bool>) and once in 176.gcc (with %struct..0anon).

4a5897fc16 Fix failure messages in Verifier::PerformTypeCheck. The argument numbers 
passed in to this function changed to support multiple return values,
leading to some incorrect argument numbers in the failure messages.
With this change, the ArgNo values used for return values and parameters are
disjoint, and the new IntrinsicParam function translates those ArgNo values
to strings that can be used in the messages.  This also fixes a few places
where PerformTypeCheck did not return false following calls to CheckFailed.

a254acd1d3 Remove alloca tracking from nocapture analysis. Not only 
was it not very helpful, it was also wrong!  The problem
is shown in the testcase: the alloca might be passed to
a nocapture callee which dereferences it and returns the
original pointer.  But because it was a nocapture call we
think we don't need to track its uses, but we do.
