Use push_back rather than operator[], which is incorrect in this cases. Unfortunately, this slow the testcase down a little bit,
but only marginally.

of after, so that any reallocation it does doesn't get counted for the pass
being timed.  This probably doesn't account for a timing discrepancy I was
looking into, but I'm fixing it anyway.

test (doesn't work for any MMX vector types, it's
not me).  Rewritten to use v2i16 which is generic
and going to stay that way; I think that preserves
the point of the test.

load,store,call,return,bitcast.  This is enough to
make call and return work.

In ConstantArray::getAsString(), we know the size of the resultant string in advance so we can pre-allocate it and just fill in
the entries.  This improves the time for the AsmPrinter on InstructionCombining.cpp from 0.4248s to 0.3370s.

We will keep the old projects/llvm-test working for existing installs.

The changes to configure are made manually, since I lack autoconf-2.6. Someone
might want to run AutoGen.sh to see if that changes anything.

All of LLVM's testing features are now referred to as the "Testing
infrastructure", the DejaGNU tests are just that, and the whole program tests
are referred to as the "test suite".

If it's determined safe, remat MOV32r0 (i.e. xor r, r) and others as it is instead of using the longer MOV32ri instruction.

where there is a use in a PHI node that's a predecessor to the defining
block. We don't want to mark all predecessors as having the value "alive" in
this case. Also, the assert was too restrictive and didn't handle this case.

Add getScaledIntervalSize, which gives a measure of the size of an interval that is independent of the scaling of
the function due to empty index slots.  This is suitable for use in backend heuristics that need to reason about the density
of an interval.
