4f41b86e7f Emit pic jumptables to the same section that the function is emitted to,
allowing label differences to work.  This fixes CodeGen/X86/pic_jumptable.ll

bf18a53eb9 Verify that jump tables are emitted to the same section as the function is,
when codegen'ing in pic mode.  This fixes a miscompilation of a switch stmt
in a template, as the template goes to a non-.text section.

c8225bc92a This case isn't implemented yet. It seems unlikely to be needed, but if it
ever is, we want to get an assert instead of silent bad codegen.

Ensure that we copy KnownProperties before calling visitBasicBlock, else
we may leak properties into blocks where they don't belong.

9b15198af4 Fix for PR929. The PHI nodes were being gone through for each instruction
in a successor block for every block...resulting in some O(N^k) algorithm
which wasn't very good for performance. Calculating this information up
front and keeping it in a map made it much faster.
