Fix live variables issues:
...
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue.
2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register:
= EAX, AX<imp-use,kill>
...
AX =
In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things.

Experimental scheduler change to schedule / coalesce the copies added for function livein's. Take 2008-03-10-RegAllocInfLoop.ll, the schedule looks like this after these copies are inserted:
...
entry: 0x12049d0, LLVM BB @0x1201fd0, ID#0:
Live Ins: %EAX %EDX %ECX
%reg1031<def> = MOVPC32r 0
%reg1032<def> = ADD32ri %reg1031, <es:_GLOBAL_OFFSET_TABLE_>, %EFLAGS<imp-def>
%reg1028<def> = MOV32rr %EAX
%reg1029<def> = MOV32rr %EDX
%reg1030<def> = MOV32rr %ECX
%reg1027<def> = MOV8rm %reg0, 1, %reg0, 0, Mem:LD(1,1) [0x1201910 + 0]
%reg1025<def> = MOV32rr %reg1029
%reg1026<def> = MOV32rr %reg1030
%reg1024<def> = MOV32rr %reg1028
The copies unnecessarily increase register pressure and it will end up requiring a physical register to be spilled.
With -schedule-livein-copies:
entry: 0x12049d0, LLVM BB @0x1201fa0, ID#0:
Live Ins: %EAX %EDX %ECX
%reg1031<def> = MOVPC32r 0

When the register allocator runs out of registers, spill a physical register around the def's and use's of the interval being allocated to make it possible for the interval to target a register and spill it right away and restore a register for uses. This likely generates terrible code but is before than aborting.

(on solaris10, which are:
CodeGen/PowerPC/frounds.ll

I needed a tool to figure out which one is the guilty.
To this end I have added a verbosity
option to the test/Makefile.
It can be invoked thus:
gmake check TESTSUITE=CodeGen/PowerPC VERBOSE="-v -v"
(The number of "-v"s specifies the verbosity level.
Instead of "-v" other aliases can be specified,
please consult the dejagnu docs for info.)
At level >= 2 following line is logged for each

Fix isNegatibleForFree to not return true for ConstantFP nodes

after legalize. Just because a constant is legal (e.g. 0.0 in SSE)
doesn't mean that its negated value is legal (-0.0). We could make

rotates are now eliminiated, other scalar-to-vector-to-scalar silliness
is also eliminated.

Add support to GVN for performing sret return slot optimization. This means that, if an sret function tail calls
...
another sret function, it should pass its own sret parameter to the tail callee, allowing it to fill in the correct
return value. llvm-gcc does not emit this by default. Instead, it allocates space in the caller for the sret of
the tail call and then uses memcpy to copy the result into the caller's sret parameter. This optimization detects
and optimizes that case.
