162726c305 Record a symbol's size which is needed for ELF symbol tables.

68a31bf9c6 ELF entry size support. 
Some ELF sections contain fixed-sized entries. Provide a way to record
the entry size of a section.

985dab611d Rename sat_shift operand to shift_imm, in preparation for using it for other 
instructions besides saturate instructions.  No functional changes.

437fea641b Partially revert r111155. It looks like MSVC is calling an operator<() that 
clang says is unused.

cc19893826 Revert r111031. The way LLVM defines loop invariance, the property of an 
expression being loop invariant is not equivalent to the property of
properly dominating the loop header.

Other optimizations have also made this optimization less important.

013400a0f9 To create a copy of a SmallVector with an element removed from the 
middle, copy the elements in two groups, rather than copying all the
elements and then doing an erase on the middle of the result. These
are SmallVectors, so we shouldn't expect to hit dynamic allocation
in the common case.

7900e1ace3 Instead of having CollectSubexpr's categorize operands as interesting or 
uninteresting, just put all the operands on one list and make
GenerateReassociations make the decision about what's interesting.
This is simpler, and it avoids an extra ScalarEvolution::getAddExpr call.

38d11cdfe0 Put add operands in ScalarEvolution-canonical order, when convenient. 
This isn't necessary, because ScalarEvolution sorts them anyway,
but it's tidier this way.

temporary ID values.

06963ff7c4 Add hooks to FoldingSetTrait to allow specializations to provide 
implementations of equality comparison and hash computation. This
can be used to optimize node lookup by avoiding creating lots of
temporary ID values just for hashing and comparison purposes.

address got DCEd.
