Preliminary support for inline asm in the cbe.  The target specific ugliness
is still in Writer, but issolated to a single function. This might be split
into something in each target directory.  This is sufficient to get through
archie and an strcpy impl on linux-x86.

Module level asm is not handled.

Change MachineInstr ctor's to take a TargetInstrDescriptor reference instead
of opcode and number of operands.

When truncating to bool, it is necessary to & with 1 for all casts that
can result in a bool. Previously PtrToInt, FPToUI and FPToSI were missing
this operation.

Removed #include <iostream> and replaced with llvm_* streams.

Alter these tests to ensure they match a "test $1, X" X86 instruction that
is now generated by the LLVM backend for "trunc to bool" instructions.

Add a test to ensure a bitcast/and/trunc combination eliminates the bitcast.

For better or worse, load from i1 is assumed to be zero extended.  Do not
