b6a4a7f72a PEI is now responsible for adding MaxCallFrameSize to frame size and align the stack. Each target can further adjust the frame size if necessary.

ab307e2180 - getTypeAlignmentShift() should be returning preferred alignment, not ABI
alignment.
- getPreferredAlignmentLog(): remove Double special case.

c5140714bc Implement a getTypeSizeInBits method. This helps in transforms that want
to ensure the bit size of a type is identical before proceeding.

4de8fa6334 TargetData assumes (and some regression tests depend on it) that the size of
an unspecified datatype in the datalayout is capped by the size of a pointer.

9df9e3e57b Teach TargetData to handle 'preferred' alignment for each target, and use
these alignment amounts to align scalars when we can.  Patch by Scott Michel!

14b42c0040 For PR1043:
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Patch by Sheng Zhou.

f6b1a88a1a - Target PIC style is no longer affected by relocation model.
- In x86-64 mode, symbols with external linkage (not just symbols which are
  defined externally) requires GOT indirect reference.

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.
