60e2650b09 Revert r59640. It broke this test for builds that aren't 
configured with llvm-gcc.

1b9557279c Use %llvmgcc -xassembler instead of invoking as directly. This avoids 
problems for example when LLVM is built with --with-extra-options=-m64
and as defaults to x86-32 mode.

a8b538544a Test passing of integer parameters for integers 
of all sizes from i1 to i256.  The code is not
always that great, for example (x86)

        movw    %ax, i17_s
where the store could be directly from %di.

c638fe5b8b For all RUN lines starting with "not", redirect stderr to /dev/null so tests 
don't fail when (expected) error output is produced. This fixes 17 tests.

While I was there, I also made all RUN lines of the form "not llvm-as..." a bit
more consistent, they now all redirect stderr and stdout to /dev/null and use
input redirect to read their input.

c4b6768db4 Remove the code from CodeGenPrepare that moved getresult instructions 
to the block that defines their operands. This doesn't work in the
case that the operand is an invoke, because invoke is a terminator
and must be the last instruction in a block.

Replace it with support in SelectionDAGISel for copying struct values
into sequences of virtual registers.

5b4101cf68 Fix isNegatibleForFree to not return true for ConstantFP nodes 
after legalize.  Just because a constant is legal (e.g. 0.0 in SSE) 
doesn't mean that its negated value is legal (-0.0).  We could make
this stronger by checking to see if the negated constant is actually
legal post negation, but it doesn't seem like a big deal.

2e9661573f Teach LegalizeTypes how to expand and promote CTLZ, 
CTTZ and CTPOP.  The expansion code differs from
that in LegalizeDAG in that it chooses to take the
CTLZ/CTTZ count from the Hi/Lo part depending on
whether the Hi/Lo value is zero, not on whether
CTLZ/CTTZ of Hi/Lo returned 32 (or whatever the
width of the type is) for it.  I made this change
because the optimizers may well know that Hi/Lo
is zero and exploit it.  The promotion code for
CTTZ also differs from that in LegalizeDAG: it
uses an "or" to get the right result when the
original value is zero, rather than using a compare
and select.  This also means the value doesn't
need to be zero extended.

36a938c4fb Crashed the new type legalizer. Not likely to catch 
any bugs in the future since to get the crash you also
need hacked in fake libcall support (which creates odd
but legal trees), but since adding it doesn't hurt...
Thanks to Chris for this ultimately reduced version.

53a98f46fd Fix some bugs in SimplifyNodeWithTwoResults where it would call deletenode to 
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
