spilling values used by an instruction in the delay slot of the branch
(which will eventually be moved before the branch).
2. Bug fix: Delete the delay slot instr, not the branch instr, when
moving delay slot instr. out!!!!
3. Move code to insert caller-saves moved here from SparcRegInfo:
it is now machine-independent.

machine-independent.
Fix problem with using branch operand reg. as temp. reg. when
spilling values used by an instruction in the delay slot of the branch
(which will eventually be moved before the branch).

now handle far calls (i.e., beyond the 30-bit limit in call instructions).
* As a side-effect, this allows us to unify and clean up the mmap() call and
code around it.

This us used by bugpoint -- when code is compiled to a shared object to be
JITted, it must use the JIT's lazy resolution method to find function addresses,
because some functions will not be available at .so load time, as they are in
the bytecode file.

Single and FP double reg types (which share the same reg class).
Now all methods marking/finding unused regs consider the regType
within the reg class, and SparcFloatRegClass specializes this code.
(2) Remove machine-specific regalloc. methods that are no longer needed.
In particular, arguments and return value from a call do not need
machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional
overloading when an include file is omitted.

Mangler.cpp: Constify parameter to makeNameProper, and use const_iterator.
Make Count an unsigned int, and use utostr().
Don't name parameters things that start with underscore.
Mangler.h: All of the above, and also: Add Emacs mode-line. Include <set>.

of codes. For example,
short kernel (short t1) {
t1 >>= 8; t1 <<= 8;
return t1;
}
became:
short %kernel(short %t1.1) {
%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.5 = cast short %tmp.3 to int ; <int> [#uses=1]
%tmp.7 = shl int %tmp.5, ubyte 8 ; <int> [#uses=1]
%tmp.8 = cast int %tmp.7 to short ; <short> [#uses=1]
ret short %tmp.8
}
before, now it becomes:
short %kernel(short %t1.1) {
%tmp.3 = shr short %t1.1, ubyte 8 ; <short> [#uses=1]
%tmp.8 = shl short %tmp.3, ubyte 8 ; <short> [#uses=1]
ret short %tmp.8
}
which will become:
short %kernel(short %t1.1) {
%tmp.3 = and short %t1.1, 0xFF00
ret short %tmp.3
}
This implements cast-set.ll:test4 and test5

doFinalization too except that would have made them shadow, not override,
the parent class :-P.
Allow *any* constant cast expression between pointers and longs,
or vice-versa, or any widening (not just same-size) conversion that
isLosslesslyConvertibleTo approves. This fixes oopack.

Printer::doFinalization() out in the cold. Now we pass in a TargetMachine
to Printer's constructor and get the TargetData from the TargetMachine.
Don't pass TargetMachine or MRegisterInfo objects around in the Printer.
Constify TargetData references.
X86.h: Update comment and prototype of createX86CodePrinterPass().
X86TargetMachine.cpp: Update callers of createX86CodePrinterPass().
