- Avoid speculatively execute vector ops.

e4f6ee590b Use push_back rather than operator[], which is incorrect in this cases. Unfortunately, this slow the testcase down a little bit, 
but only marginally.

153d28a414 Append to the ActiveTimers std::vector before looking at the timer instead 
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.

4a103e6d7e v2f32 is now a valid (MMX) type which breaks this 
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.

a68f9013f2 Add v2f32 (MMX) type to X86. Support is primitive: 
load,store,call,return,bitcast.  This is enough to
make call and return work.

45e3958941 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.

5b80c663e7 Allow the test suite to be checked out into projects/test-suite. 
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.

are referred to as the "test suite".

ebcba612b5 This situation can occur: 
,------.
    |      |
    |      v
    |   t2 = phi ... t1 ...
    |      |
    |      v
    |   t1 = ...
    |  ... = ... t1 ...
    |      |
    `------'

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.

72e04099c6 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.
