Subzero: Change -asm-verbose output to print more useful info.
Frame offsets for variables are emitted using a symbolic name based on the variable's name. This makes it a bit easier to digest the asm code.
For example, if variable Foo gets an esp offset 24, asm like this:
... 24(%esp) ...
will instead be emitted like this:
lv$Foo = 24
...
... lv$Foo(%esp) ...
Predecessor labels are printed for each basic block.
Loop nest depth is printed for each basic block. (Would be nice if we had loop header info as well.)
