The fix is obvious and the only test case I have is horrible, so I am
not including it. The problem shows up when self-hosting clang on i386
with -new-coalescer enabled.

If the width is very large it gets truncated from uint64_t to uint32_t when
passed to TD->fitsInLegalInteger. The truncated value can fit in a register.
This manifested in massive memory usage or crashes (PR13946).

folders and not having it here fails to compile if you actually try to use it.

Also, CreatePointerCast was failing to do the part where it does TD-aware
constant folding. Granted there is exactly one case where that it will ever
do anything, but there's no reason to skip it. For reference, that case is a
subtraction between two constant offsets on the same global variable, eg.,
"&A[123] - &A[4].f".

This is a preliminary step towards ELF support; currently ARMFastISel hasn't
been used for ELF object files yet.

This method can be called with a '0' argument which checks the return
value. However, the method it calls doesn't expect '0' as a valid value. Call the
correct method when it's 0.

The hasFnAttr method has been replaced by querying the Attributes explicitly. No
intended functionality change.

If the offset is more than 24-bits, it won't fit in a scattered
relocation offset field, so we fall back to using a non-scattered
relocation.

This opaque class will contain all of the attributes. All attribute queries will
go through this object. This object will also be uniqued in the LLVMContext.

APFloat::roundToIntegral: Special values don't keep the exponent value up to date, don't rely on it.

Add a couple of unit tests for special floats. Fixes 13929, found by MemorySanitizer.
