shifting only makes sense for positive values of b. The previous patch did
not consider this as isl currently always produces postive b's. To avoid future
surprises, we check that b is positive and only then apply the optimization.
We also now correctly check the return value of the dyn-cast.
No additional test case, as isl currently does not produce negative
denominators.

Re-commit r238838, r238844 with fix for host/target endian mismatch and windows buildbot.
The windows buildbot originally failed because the check expressions are
evaluated as 64-bit values, even for 32-bit symbols. Fixed this by comparing
bottom 32-bits of the expressions.
The host/target endian mismatch issue is that it's invalid to read/write target
values using a host pointer without taking care of endian differences between
the target and host. Most (if not all) instances of
reinterpret_cast<uint32_t*>() in the RuntimeDyld are examples of this bug.
This has been fixed for Mips using the endian aware read/write functions.

Avoid saying this is based on sections because it's not very accurate.
That we don't split section into smaller chunks of data does not mean
that the linker is built on top of that.
In reality, most part of the code do not care about underlying data,
so they are neither based on "atoms" nor sections.
The symbol table only cares about symbol names and their types.
The writer handles list of chunks, which look like just blobs,
and the writer doesn't care what those chunks are backed by.

If the value is non-zero, it represents a string table index that gives the
symbol name. Otherwise, the symbol table entry has no name.
