a027ba885a Fix test/Regression/ExecutionEngine/2005-12-02-TailCallBug.ll and PR672. 
This also fixes 177.mesa, the only program that fails with --enable-x86-fastcc
turned on.  Given a clean nightly tester run, we should be able to turn it
on by default!

fe14b34d83 Don't remove two operand, two result nodes from the binary ops map. These

c5e6c649b5 This is a bugfix for SelectNodeTo. In certain situations, we could be 
selecting a node and use a mix of getTargetNode() and SelectNodeTo.  Because
SelectNodeTo didn't check the CSE maps for a preexisting node and didn't insert
its result into the CSE maps, we would sometimes miss a CSE opportunity.

This is extremely rare, but worth fixing for completeness.

f43a3ca26d First chunk of actually generating vector code for packed types. These 
changes allow us to generate the following code:

_foo:
        li r2, 0
        lvx v0, r2, r3
        vaddfp v0, v0, v0
        stvx v0, r2, r3
        blr

for this llvm:

void %foo(<4 x float>* %a) {
entry:
        %tmp1 = load <4 x float>* %a
        %tmp2 = add <4 x float> %tmp1, %tmp1
        store <4 x float> %tmp2, <4 x float>* %a
        ret void
}

7f0db91f86 All sorts of stuff. 
Getting in on the custom lowering thing, yay
evilness with fp setcc, yuck
trivial int select, hmmm
in memory args for functions, yay
DIV and REM, always handy.  They should be custom lowered though.

Lots more stuff compiles now (go go single source!).  Of course, none of it
probably works, but that is what the nightly tester can find out :)

6ff7240a5c Fix a problem with llvm-ranlib that (on some platforms) caused the archive 
file to become corrupted due to interactions between mmap'd memory segments
and file descriptors closing. The problem is completely avoiding by using
a third temporary file.
