e821eb23cd This testcase is dead. It doesn't inline even if I add the 'alwaysinline' 
attribute to the @foo function.

cfc77bc719 When promoting integer vectors we often create ext-loads. This patch adds a 
dag-combine optimization to implement the ext-load efficiently (using shuffles).

For example the type <4 x i8> is stored in memory as i32, but it needs to
find its way into a <4 x i32> register. Previously we scalarized the memory
access, now we use shuffles.

4149334f09 Synthesize x86 max/min instructions also for vectors (i.e. produce 
maxps and maxpd).  This broke the sse41-blend.ll testcase by causing
maxpd to be produced rather than a cmp+blend pair, which is the reason
I tweaked it.  Gives a small speedup on doduc with dragonegg when the
GCC vectorizer is used.
