d3c7b7359d Make the key of ValueRankMap an AssertingVH, so that we die violently 
if it dangles.

f4978e2094 This pass keeps a map of Instructions to Rank numbers, 
and was deleting Instructions without clearing the
corresponding map entry.  This led to nondeterministic
behavior if the same address got allocated to another
Instruction within a short time.

03afd02ca2 Don't assign rank numbers to debug intrinsic "calls". 
This is needed so debug info doesn't change codegen.

3e15bf33e0 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

42a7551725 rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger. 
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)

7b4ad94282 Fix a problem that Dan Berlin noticed, where reassociation would not succeed 
in building maximal expressions before simplifying them.  In particular, i
cases like this:

X-(A+B+X)

the code would consider A+B+X to be a maximal expression (not understanding
that the single use '-' would be turned into a + later), simplify it (a noop)
then later get simplified again.

Each of these simplify steps is where the cost of reassociation comes from,
so this patch should speed up the already fast pass a bit.

Thanks to Dan for noticing this!
