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.

Change the MemoryBuffer::getFile* methods to take just a pointer to the

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.
