b4dc0233c9 Convert CodeGen/*/*.ll tests to use the new CHECK-LABEL for easier debugging. No functionality change and all tests pass after conversion.
This was done with the following sed invocation to catch label lines demarking function boundaries:
    sed -i '' "s/^;\( *\)\([A-Z0-9_]*\):\( *\)test\([A-Za-z0-9_-]*\):\( *\)$/;\1\2-LABEL:\3test\4:\5/g" test/CodeGen/*/*.ll
which was written conservatively to avoid false positives rather than false negatives. I scanned through all the changes and everything looks correct.

a87dea4f8c switch off of 'Section' onto MCSection. We're not properly using
MCSection subclasses yet, but this is a step in the right direction.

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:

2ac8b324eb Fix for PR4235: to build a floating-point value from integer parts,
build an integer and cast that to a float.  This fixes a crash 
caused by trying to split an f32 into two f16's.

This changes the behavior in test/CodeGen/XCore/fneg.ll because that 
testcase now triggers a DAGCombine which converts the fneg into an integer
operation.  If someone is interested, it's probably possible to tweak 
the test to generate an actual fneg.

51d83fdd89 Reapply r59464, this time using the correct type
when softening FNEG.

7fed65a68d Add soft float support for a bunch more operations. Original
patch by Richard Osborne, tweaked and extended by your humble
servant.
