Fix wierd problems linking C programs which look for symbols in libstdc++.
This was due to the 'assert' macro expanding into a function call on some
platforms which could throw.  The C++ compiler then added checks for the
exception specifications in these functions, which pulled in the C++ runtime.
This was bad, and the assertions can never fire (the library is now debugged)
so just remove them.

New testcase for masking operation that frequently occurs in the pool allocator
for converting a number that is a power of two into a mask

Update documentation since it was misleading: make it clear that a
negative instruction count is returned if instructions are removed
from a basic block.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@9705 91177308-0d34-0410-b5e6-96231b3b80d8

Change all machine basic block modifier functions in MRegisterInfo to
return the number of instructions added to/removed from the basic block
passed as their first argument.

Note: This is only needed because we use a std::vector instead of an
ilist to keep MachineBasicBlock instructions. Inserting an instruction
to a MachineBasicBlock invalidates all iterators to the basic
block. The return value can be used to update an index to the machine
basic block instruction vector and circumvent the iterator elimination
problem but this is really not needed if we move to a better
representation.

Update verifySavedState()'s comment, so that it reflects its current
status.  In doFinalization(), skip over external functions, just like
Anand's mapping info does.
