History
Chandler Carruth 4afa2b842b Major update to CMake build to reflect changes in r135219 in the 
backend. Moved some MCAsmInfo files down into the MCTargetDesc
sublibraries, removed some (i suspect long) dead files from other parts
of the CMake build, etc. Also copied the include directory hack from the
Makefile.

Finally, updated the lib deps. I spot checked this, and think its
correct, but review appreciated there.

README.txt 

***

add gcc builtins for alpha instructions


***

custom expand byteswap into nifty 
extract/insert/mask byte/word/longword/quadword low/high
sequences

***

see if any of the extract/insert/mask operations can be added

***

match more interesting things for cmovlbc cmovlbs (move if low bit clear/set)

***

lower srem and urem

remq(i,j):  i - (j * divq(i,j)) if j != 0
remqu(i,j): i - (j * divqu(i,j)) if j != 0
reml(i,j):  i - (j * divl(i,j)) if j != 0
remlu(i,j): i - (j * divlu(i,j)) if j != 0

***

add crazy vector instructions (MVI):

(MIN|MAX)(U|S)(B8|W4) min and max, signed and unsigned, byte and word
PKWB, UNPKBW pack/unpack word to byte
PKLB UNPKBL pack/unpack long to byte
PERR pixel error (sum across bytes of bytewise abs(i8v8 a - i8v8 b))

cmpbytes bytewise cmpeq of i8v8 a and i8v8 b (not part of MVI extensions)

this has some good examples for other operations that can be synthesised well 
from these rather meager vector ops (such as saturating add).
