This is a work in progress.

not all unary nodes necessarily have a simple result type.

MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

allocated and thus not freed.  This is cool except that it contains
and std::string so the string data didn't get freed.  In any case
there is no reason to redundantly store the string data in the 
MCSymbol anyway, just make the MCSymbol ref the string data in the
MCContext StringMap.

llvm-svn: 98536

now enforces that input/output named values have hte same type.

llvm-svn: 98535

changing the primary datastructure from being a 
"std::vector<unsigned char>" to being a new TypeSet class
that actually has (gasp) invariants!

This changes more things than I remember, but one major
innovation here is that it enforces that named input 
values agree in type with their output values.

This also eliminates code that transparently assumes (in 
some cases) that SDNodeXForm input/output types are the
same, because this is wrong in many case.

This also eliminates a bug which caused a lot of ambiguous
patterns to go undetected, where a register class would
sometimes pick the first possible type, causing an
ambiguous pattern to get arbitrary results.

With all the recent target changes, this causes no 
functionality change!

to re-instrument the code.  We depend on the system valgrind.h to
avoid adding a new license.

llvm-svn: 98528

doesn't have a type constraint on the scalar because we don't have
an 'sAny' type.

llvm-svn: 98523

fix the rest of the buildbot failures on non-x86 hosts.

llvm-svn: 98522

on hosts without cmovs.

llvm-svn: 98521

(at least) on non-x86 builders.

with ppc_f128 type by having the type legalizer turn these back into a
call to copysignl.
