41d08a0bbe Get rid of all symbolic loads. I now do gernate all relocations sequences
rather than relying on the assembler.  Only a few more pseudo instructions
left.  Also merge load code paths.

a3f70592a7 Reduce use of pseudo ops
Namely, output the rellocation flags explicitly when loading constants.
Added benifit: save a load when loading from the constant pool.

e54b651806 Make it easier to find alpha stuff in doxygen, and fixup labeling
of memory instructions in the assembly, to allow later linking
of traces with LLVM Value*s.

8b64bd0fd5 Implement count leading zeros (ctlz), count trailing zeros (cttz), and count
population (ctpop).  Generic lowering is implemented, however only promotion
is implemented for SelectionDAG at the moment.

More coming soon.

5bd65ee784 two things: 1)evilness reduction patch, reduces the number of instructions hiding in the small jump CC moving code. 2)implement div of small data types by FP DIV (also reduces evilness and should speed things up)

56c441caf2 so, if you beat on it, you too can talk emacs into having a sane indenting policy... Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)
