d5508bfe28 verify-uselistorder: Change the default -num-shuffles=5 
Change the default for `-num-shuffles` to 5 and better document the
algorithm in the header docs of `verify-uselistorder`.

f58c944271 verify-uselistorder: Add RUN lines to cases in test/Assembly 
Add RUN line for `verify-uselistorder` to every test in `test/Assembly`,
unless it's a negative check (assembler rejects it) or verification
fails.

There are three files that verification fails on (so I've left out the
RUN lines):

  - 2002-08-22-DominanceProblem.ll
  - ConstantExprFold.ll
  - ConstantExprFoldCast.ll

This is part of PR5680.

74351693ea Modify the LLVM assembly output so that it uses references to represent function attributes. 
This makes the LLVM assembly look better. E.g.:

     define void @foo() #0 { ret void }
     attributes #0 = { nounwind noinline ssp }

9f526bcf4d First step in fixing PR8927: 
Add a unnamed_addr bit to global variables and functions. This will be used
to indicate that the address is not significant and therefore the constant
or function can be merged with others.

If an optimization pass can show that an address is not used, it can set this.

Examples of things that can have this set by the FE are globals created to
hold string literals and C++ constructors.

Adding unnamed_addr to a non-const global should have no effect unless
an optimization can transform that global into a constant.

Aliases are not allowed to have unnamed_addr since I couldn't figure
out any use for it.
