d655075e9d Remove unneeded code now that splitBasicBlock does the "right thing"

840109cd9c When splitting a basic block, insert the new half immediately after the first 
half.

8f0a362cd4 More refactoring. Move alloca instructions and handle invoke instructions 
before we delete the original call site, allowing slight simplifications of
code, but nothing exciting.

ab01a0e982 Move the cloning of the function body much earlier in the inlinefunction 
process.  The only optimization we did so far is to avoid creating a
PHI node, then immediately destroying it in the common case where the
callee has one return statement.  Instead, we just don't create the return
value.  This has no noticable performance impact, but paves the way for
future improvements.

aa44b4de3e Give CloneBasicBlock an optional function argument to specify which function 
to add the cloned block to.  This allows the block to be added to the function
immediately, and all of the instructions to be immediately added to the function
symbol table, which speeds up the inliner from 3.7 -> 3.38s on the PR209.

1404b61b62 In BasicBlock::splitBasicBlock, just use islist::splice to move the instructions, 
instead of a loop that is really inefficient with large basic blocks.

This speeds up the inliner pass on the testcase in PR209 from 13.8s to 2.24s
which still isn't exactly speedy, but is a lot better.  :)

2998d508b0 Bunch up all locally used allocas by the block they are allocated in, and 
process them all as a group.  This speeds up SRoA/mem2reg from 28.46s to
0.62s on the testcase from PR209.

a61cda01c2 Second half of a fix for PR218 & test/Regression/Assembler/2004-02-01-NegativeZero.llx. 
Basically we store floating point values as their integral components, instead of relying
on the semantics of floating point < to differentiate between values.  This is likely to
make the map search be faster anyway.
