While I'm here, fix the related issue with strncmp, add some actual tests for strcmp and strncmp, and start using StringRef::compare for constant folding instead of using strcmp/strncmp so that the optimized IR isn't dependent on the host's implementation of strcmp.

Stop emitting instructions with the name "tmp" they eat up memory and have to be uniqued, without any benefit.2011-09-27T20:39:19ZBenjamin Kramerbenny.kra@googlemail.com2011-09-27T20:39:19Zurn:sha1:a9390a4d5f5d568059a80970d22194b165d097a7
If someone prefers %tmp42 to %42, run instnamer.

Move "atomic" and "volatile" designations on instructions after the opcode2011-08-12T22:50:01ZEli Friedmaneli.friedman@gmail.com2011-08-12T22:50:01Zurn:sha1:f03bb260c90ad013aa4e55af36382875011c95b8
of the instruction.
Note that this change affects the existing non-atomic load and store
instructions; the parser now accepts both forms, and the change is noted
in the release notes.

rip out a ton of intrinsic modernization logic from AutoUpgrade.cpp, which is2011-06-18T06:05:24ZChris Lattnersabre@nondot.org2011-06-18T06:05:24Zurn:sha1:b85e4eba85a38698f3b3332f82554bf8442547e2
for pre-2.9 bitcode files. We keep x86 unaligned loads, movnt, crc32, and the
target indep prefetch change.
As usual, updating the testsuite is a PITA.
