by dropping all references from all constants that can use other
constants before trying to destroy any of them.
I also had to free bugpoint's Module in ~BugDriver().

don't care about leaks from tblgen, and I assume we don't care about
valgrind errors in llvm-gcc/g++.

of runs without leak checking. We add -vg to the triple for non-checked runs,
or -vg_leak for checked runs. Also use this to XFAIL the TableGen tests, since
tablegen leaks like a sieve. This includes some valgrindArgs refactoring.

with changes to add a separate optional register update argument. Change all
the NEON instructions with address register writeback to use it.

writeback, and refactor the existing double-spaced VST2 instructions.
These are only for the disassembler since codegen doesn't use them, at
least for now.

load/stores with address register writeback, and use "odd" suffix to distinguish
instructions to access odd numbered registers (instead of "a" and "b").
No functional changes.

load/store optimizer would incorrectly think that registers D26 and D28
were consecutive and would generate a VLDM instruction to load them.
The assembler was not convinced.

so that the SCEVExpander doesn't retain a dangling pointer as its
insert position. The dangling pointer in this case wasn't ever used
to insert new instructions, but it was causing trouble with
SCEVExpander's code for automatically advancing its insert position
past debug intrinsics.
This fixes use-after-free errors that valgrind noticed in
test/Transforms/IndVarSimplify/2007-06-06-DeleteDanglesPtr.ll and
test/Transforms/IndVarSimplify/exit_value_tests.ll.

caller, then it is not safe to optimize the call into a sibcall since
the call result has to be popped off the x87 stack.

to maintain a list of types (one for each result of
the node) instead of a single type. There are liberal
hacks added to emulate the old behavior in various
situations, but they can start disolving now.
