b34e3a9b6b whitespace cleanups, make the MipsAsmPrinter::doInitialization
chain to the super class instead of initializing mangler directly.
This gives it .file and module level inline asm support among other
things.

d3ffc06174 fix Sparc, SystemZ, and MSP430 to not override AsmPrinter::doInitialization.
This eliminates redundancy setting up the mangler and adds support to them
for module-level inline asm and a .file directive.

5026ae4514 Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

f241174421 Revert the addition of hasNoPointerOverflow to GEPOperator.
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.

Remove a few optimizations that depended on this flag.

being more consistent with other backends, this makes the SPARC backend 
deal with functions with arguments with illegal types correctly, which 
fixes some tests in test/CodeGen/Generic.

Inline asm instructions may have additional <imp-def,kill> register operands.
These operands are not marked with a flag like the normal asm operands, so we
must not assert that there is a flag.

796492dc4b Switch Alpha over to the new call lowering style. New code mostly
copied from the SystemZ target.  I don't think this causes any 
significant changes to the output (I compared the assembly, and the 
results appeared to be essentially unchanged), although I don't actually 
have an Alpha to test on.

I would appreciate if anyone with the appropriate hardware could test 
this. I'm not sure if that includes anyone subscribed to llvm-commits, 
though.

e2cf37b88c Untangle a snarl that I discovered when updating the mangler,
starting in getCurrentFunctionEHName.  Among other problems,
we would try to privative a "foo.eh" label, but end up emitting
the label as _Lfoo.eh instead of L_foo.eh on darwin.  This is really
bad, and the linker has always tolerated these labels existing.
For now, just emit them as _foo.eh.

This patch also fixes problems with ".eh" labels on unnamed
functions and eliminates two strangely defined TargetAsmInfo
hooks.

32360a7e21 Add line numbers to OProfile. To do this, I added a processDebugLoc()
call to the MachineCodeEmitter interface and made copying the start
line of a function not conditional on whether we're emitting Dwarf
debug information. I'll propagate the processDebugLoc() calls to the
non-X86 targets in a followup patch.

In the long run, it'll probably be better to gather this information
through the DwarfWriter, but the DwarfWriter currently depends on the
AsmPrinter and TargetAsmInfo, and fixing that would be out of the way
for this patch.

There's a bug in OProfile 0.9.4 that makes it ignore line numbers for
addresses above 4G, and a patch fixing it at
http://thread.gmane.org/gmane.linux.oprofile/7634

57e599a46b Teach MachineInstr::isRegTiedToDefOperand() to correctly parse inline asm operands.
The inline asm operands must be parsed from the first flag, you cannot assume
that an immediate operand preceeding a register use operand is the flag.
PowerPC "m" operands are represented as (flag, imm, reg) triples.
isRegTiedToDefOperand() would incorrectly interpret the imm as the flag.
