2509765bef * Fix one more bug in PIC codegen: extra load is needed for *all*
non-statics.
* Introduce new option to output zero-initialized data to .bss section.
This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.

5789edd7f5 New "TargetObjInfo" class. This holds information that the object writers will
use to write things to the file. It's abstract so each target should implement
its own version for each writer type.

cfdd717db5 Fix for PR1095:
LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound
inline asm expression.

373d2bccea For PR1064:
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

38cb858ee5 - Remove isSetCCExpensive() etc. These are no longer used.
- Add isSelectExpensive() etc. It's used to tell codegen that select is expensive for a given target, avoid using it if possible. Currently it's only
used to expand FCOPYSIGN.

3eb79afad9 Add virtual method spillCalleeSaveRegisters() and restoreCalleeSaveRegisters()
to MRegisterInfo. These allow the target to issue instructions to spill and
restore callee saved registers in case where individual stores / loads aren't
the correct / profitable choice.

7f6a73eb5c Added an automatic cast to "std::ostream*" etc. from OStream. We then can
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.
