1530481dd3 Add a version of AddString that takes a const char* so we can avoid extraneous 
conversions to std::string.

a08868acb3 Append to the ActiveTimers std::vector before looking at the timer instead 
of after, so that any reallocation it does doesn't get counted for the pass
being timed.  This probably doesn't account for a timing discrepancy I was
looking into, but I'm fixing it anyway.

1de28ac425 First step to fix PR2088. Implement routine to compute the 
multiplicative inverse of a given number. Modify udivrem to allow input and 
output pairs of arguments to overlap. Patch is based on the work by Chandler
Carruth.

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.

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.
