24604110ef reapply my strstr optimization. I have reproduced the x86-64 bootstrap
miscompile (i386.o miscompares) but it happens both with and without
this patch.

0001517d9d revert my strstr optimization, I'm told it breaks x86-64 bootstrap.
Will reapply with a fix when I get a chance.

e9f9a7e10e In C++, code is not allowed to call main. In C it is, this
simplifylibcalls optimization is thus valid for C++ but not C.
It's not important enough to worry about for C++ apps, so just
remove it.

ae3a0be92e Split the Add, Sub, and Mul instruction opcodes into separate
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

eacb7020ec For PR950:
Update the test suite to accommodate the change from signed integer types
to signless integer types. The changes were of only a few kinds:

1. Make sure llvm-upgrade is run on the source which does the bulk of the
   changes automatically.

2. Change things like "grep 'int'" to "grep 'i32'"

3. In several tests bitcasting caused the same name to be reused in the
   same type plane. These had to be manually fixed. The fix was (generally)
   to leave the bitcast and provide the instruction with a new name. This
   should not affect the semantics of the test. In a few cases, the
   bitcasts were known to be superfluous and irrelevant to the test case
   so they were removed.

4. One test case uses a bytecode file which needed to be updated to the
   latest bytecode format.
