c7e3069bfa Fix the .ll grammar rules to allow any type before an 'i32', not just an 
integer type.  Invalid things like 'float 42' are now rejected by the
semantic analysis in the productions not the parser.  This fixes PR2733.

7f04268176 - Add target lowering hooks that specify which setcc conditions are illegal, 
i.e. conditions that cannot be checked with a single instruction. For example,
SETONE and SETUEQ on x86.
- Teach legalizer to implement *illegal* setcc as a and / or of a number of
legal setcc nodes. For now, only implement FP conditions. e.g. SETONE is
implemented as SETO & SETNE, SETUEQ is SETUO | SETEQ.
- Move x86 target over.

7b8e96401c When doing the very-late shift-and address-mode optimization, 
create a new DAG node to represent the new shift to keep the
DAG consistent, even though it'll almost always be folded into
the address.

If a user of the resulting address has multiple uses, the
nodes may get revisited by a later MatchAddress call, in which
case DAG inconsistencies do matter.

This fixes PR2849.

-fast-isel=false disables it. Fast-isel is also on by default
with -fast, and off by default otherwise.

96f945267c Actually run Obj-C++ tests if llvm-gcc supports. 
Before there were two problems: (1) configure
turned "obj-c++" into "obj" in the langs line;
(2) the dejagnu library called it objc++ not
obj-c++.
Now the problem is that some of these tests don't
pass!

46292be362 Revert commit 56835 since it breaks the build. 
"If a re-materializable instruction has a register
operand, the spiller will change the register operand's
spill weight to HUGE_VAL to avoid it being spilled.
However, if the operand is already in the queue ready
to be spilled, avoid re-materializing it".
