Fix a bug in the DAGCombiner's handling of multiple linked
...
MERGE_VALUES nodes. Replacing the result values with the
operands in one MERGE_VALUES node may cause another
MERGE_VALUES node be CSE'd with the first one, and bring
its uses along, so that the first one isn't dead, as this
code expects. Fix this by iterating until the node is
really dead. This fixes PR4699.

Fix a weird ppc64-specific link error during an llvm-gcc build:
...
ld: bad offset (0x00000091) for lo14 instruction pic-base fix-up in ___popcountdi2 from libgcc/./_popcountsi2_s.o
The problem is that the non lazy symbol pointers need to be 8 byte aligned
on ppc64 and .section doesn't have an implicit alignment like ".non_lazy_symbol_pointer"
does.

Make the big switch: Change MCSectionMachO to represent a section *semantically*
...
instead of syntactically as a string. This means that it keeps track of the
segment, section, flags, etc directly and asmprints them in the right format.
This also includes parsing and validation support for llvm-mc and
"attribute(section)", so we should now start getting errors about invalid
section attributes from the compiler instead of the assembler on darwin.
Still todo:
1) Uniquing of darwin mcsections
2) Move all the Darwin stuff out to MCSectionMachO.[cpp|h]
3) there are a few FIXMEs, for example what is the syntax to get the
S_GB_ZEROFILL segment type?
