f0339396c1 IMULri* instructions do not require their first two registers operands
to be the same (IOW they are not two address instructions).

44a6807f4f Optimize the case where we are inlining a function that contains only one basic block,
and that basic block ends with a return instruction.  In this case, we can just splice
the cloned "body" of the function directly into the source basic block, avoiding a lot
of rearrangement and splitBasicBlock's linear scan over the split block.  This speeds up
the inliner on the testcase in PR209 from 2.3s to 1.7s, a 35% reduction.

3fb57b691d Delete the BasicBlock ctor that only takes a BasicBlock to insert before. This
fails when the basic block points to the function->end.  Instead, require that
the client pass in the function AND the basicblock to insert into.

5e923dee60 More refactoring. Move alloca instructions and handle invoke instructions
before we delete the original call site, allowing slight simplifications of
code, but nothing exciting.

5052c911ec 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.

23b4c68f46 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.

f2c3106866 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.  :)

cfdf2419bc 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.
