e14d81deeb Add some basic Pool-allocation infrastructure. This adds a Recycler class,
for handling bookkeeping for deleted objects, as well as the alist class
template, for keeping lists of objects allocated from Recyclers, and some
related utilities.

153d28a414 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.

300c6c5167 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.

bfde7d6b9e 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.

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,
