365f54c7bc Convert a few assertions with side-effects into regular old runtime checks.
These side-effects seem to make a difference when using llc -march=sparcv9
in Release mode (i.e., with -DNDEBUG); when they are left out, lots of
instructions just get dropped on the floor, because they never end up
in the schedule.

1b4aeb5cec As it happens, none of these TargetInstrInfo methods which are only
used in the SparcV9 backend really have anything to do with
TargetInstrInfo, so we're converting them into regular old global
functions and moving their declarations to SparcV9InstrSelectionSupport.h.
(They're mostly used as helper functions for SparcV9InstrSelection.)

a9d790c831 Temporarily disable this code, as it is emitting LLVM_NAN("nan") which results in a call to the
glibc 'nan' function because the initializer is not a string.  This breaks when used in a global
initializer.  Try compiling this testcase for example:

%X = global float <some nan value>

42df461c90 Make sure to emit the immediate byte for instructions like:
shrd [mem], reg, imm

This fixes the jit-ls failure on 186.crafty.

bebde759e5 * Use LI(S) to copy constants into registers intead of ADDI(S) as the latter is
a funky way to "use" R0 for a 0-valued operand
* Add IMPLICIT_DEFs for incoming function arguments via registers to help the
  register allocator not clobber those registers
* Implement comparisons with longs
* Teach emitSelectOperation() to fold the SetCC operation
