515674c7b6 Round up stack to multiple of alignment only if it's a leaf function without alloca.

5ad334fbda Last check-in was bogus. There is no need to align the stack if the function is a leaf function (and without alloca).

c10305743c 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.

ae19abc2cc - 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.
- Stylistic code clean up.

5032e5a613 * 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.

34f03fff2d 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.

the X86 and PPC backends. It defaults to "0", the first variant of a compound

42a7551725 rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger. 
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)
