0d32cd97e1 As comments said, for negative value, the arithmetic
over-shift-right should return -1. So here it should be signed-extended,
when bitwidth larger than 64.

9fc9250ec0 Give a proper error message when a command line option is defined more than
once (ie, at two different places in the source, not two times on the
commandline).

several things that were neither in an anonymous namespace nor static
but not intended to be global.

675fca3ee1 Check that APFloat::convert is not trying to target
ppc long double, which doesn't work.

This may break some stuff temporarily, but I want to
avoid the propagation of code that assumes this works.

d141d16ed7 Change the MemoryBuffer::getFile* methods to take just a pointer to the
start of a filename, not a filename+length.  All clients can produce a
null terminated name, and the system api's require null terminated 
strings anyway.

7f88d9043f Reimplement MemoryBuffer::getFile with three enhancements:
1) stop using MappedFile.
2) if profitable use the sys::path::MapInFilePages api to
   read the file.
3) otherwise fallback to read.

When sys::path::MapInFilePages is implemented, this provides
several benefits:

#1: this avoids fragmenting memory for small files.
#2: this avoids extraneous stat calls when the file size is known.
#3: this only keeps the file descriptor open while reading the 
    file, not for the duration of the lifetime of the memory 
    buffer.  This fixes a serious clang FD 'leak' problem.

I believe that this will work on a win32 machine, but I don't have
one to test on.  I'd appreciate it if someone could check.

c88457a8b2 Change DiffFilesWithTolerance to be written in terms of MemoryBuffer,
not an mmapped file.  This more closely matches its requirements and
provides an implicitly null terminated buffer, something this
routine had to emulate itself before.

f2309c208a Remove MappedFile support for mapping files for write and exec
and shared.  This complicates the design, is not used, and probably
doesn't even work.

f06b7ac532 Added "Profile" method to APFloat for use with FoldingSet.
Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary
objects to a profile via dispatch to FoldingSetTrait<T>::Profile().

Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their
functionality is now replaced using the above mentioned member template.
