038112a4e0 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.


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49041 91177308-0d34-0410-b5e6-96231b3b80d8

11da4cf25c 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.

a7750c1142 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.

bdbd2d710c 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.

Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary

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

0a3fecad0a Made 'FoldingSetNodeID' a proper class instead of a nested class in 
'FoldingSetNodeImpl' (previously 'FoldingSetNodeID' was a typedef of
'FoldingSetNodeImpl::NodeID').

Why?  Clients can now easily forward declare 'FoldingSetNodeID' without having
to include FoldingSet.h.

ee7ae384f5 When converting to integer, do bit manipulations in the destination 
memory rather than in a copy of the APFloat.  This avoids problems
when the destination is wider than our significand and is cleaner.

Also provide deterministic values in all cases where conversion
fails, namely zero for NaNs and the minimal or maximal value
respectively for underflow or overflow.

686700e325 Fast-track obviously over-large and over-small exponents during decimal-> 
integer conversion.  In some such cases this makes us one or two orders
of magnitude faster than NetBSD's libc.  Glibc seems to have a similar
fast path.

Also, tighten up some upper bounds to save a bit of memory.
