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.

9ffd19af2e Implement Path::MapInFilePages/UnMapFilePages on unix, which
provides fast MappedFile::getFile for large files.

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.

540630f637 cleanup the MappedFile API and comments. This removes and updates
tons of out of date comments (really nothing throws here!) and fixes
some other fairly glaring issues: "size" used to return the size of 
the file *and* change it, depending on how you called it.

1544e4713b Emit exception handling info for functions which are
not marked nounwind, or for all functions when -enable-eh
is set, provided the target supports Dwarf EH.

llvm-gcc generates nounwind in the right places; other FEs
will need to do so also.  Given such a FE, -enable-eh should
no longer be needed.

random reasons (e.g. looking for 'or' or counting lines

24d2f8a212 The support for remat of instructions with a register operand is hackish, to say the least. Since the register operand guaranteed to be PIC base and that it is already live at all uses, we are making sure it will not be spilled after its uses are rematerialized for both performance and correctness reasons.
