Massive check in. This changes the "-fast" flag to "-O#" in llc. If you want to
use the old behavior, the flag is -O0. This change allows for finer-grained
control over which optimizations are run at different -O levels.

Most of this work was pretty mechanical. The majority of the fixes came from
verifying that a "fast" variable wasn't used anymore. The JIT still uses a
"Fast" flag. I'll change the JIT with a follow-up patch.

Now that any size of integer indices are allowed for sequential types, remove the unneccessary gyan about promoting them.

BLOCKNAME and SETRECORDNAME.  This allows a bitcode
file to be self describing with pretty names for 
records and blocks in addition to numbers.  This
enhances llvm-bcanalyzer to use this to print prettily.

Any size of integral indices are allowed in gep for indexing into sequential types. Also adding a test case to check the indices type allowed into struct.

Make BinOps typed and require a type specifier for !nameconcat.  This
allows binops to be used in typed contexts such as when passing
arguments to classes.
