a7fc820079 Remove hack used to strip unwanted chars from section name 
Use MCSectionELF methods as much as possible, removing some
ELFWriter methods which are now unused

62eec42595 TargetRegistry: Reorganize AsmPrinter construction so that clients pass in the 
TargetAsmInfo. This eliminates a dependency on TargetMachine.h from
TargetRegistry.h, which technically was a layering violation.
 - Clients probably can only sensibly pass in the same TargetAsmInfo as the
   TargetMachine has, but there are only limited clients of this API.

c692477e5e Set raw_os_ostream, raw_string_ostream, and raw_svector_ostream to be 
unbuffered. std::ostream does its own buffering, and std::string and
SmallVector both have allocation strategies intended to handle frequent
appending.

4ac7200d66 Add support to raw_ostream for sizing the buffer according to the 
needs of the underlying output mechanism. raw_fd_ostream now uses
st_blksize from fstat to determine a buffer size.

3469d2e1a9 Fix the buffer handling logic so that write_impl is always called with 
a full buffer, rather than often being called with a
slightly-less-than-full buffer.

d559e66749 Fix a 4x slowdown in llc -asm-verbose caused by the use of 
WriteAsOperand in more places.

Now that more things are using WriteAsOperand, its behavior of
constructing a TypePrinting object and populating it with strings for all
the numbered types in the Module on each call is a significant bottleneck.
Fancier solutions could be pursued here, but for now, just bypass the
TypePrinting overhead in obvious cases.

implemented somewhat differently than before, but it should have
the same functionality and the previous testcase passes again.

d56e4482fc When InstCombine simplifies a load -> extract element to gep -> load, place 
the new load by the old load instead of by the extract element because
a store could have occurred between the load and extract element.
