Maintaining CONST_COPY Instructions until Pre Emit may prevent some ifcvt case
and taking them in account for scheduling is difficult for no real benefit.

[[noreturn]] function are not required to also be [[noreturn]]. We still emit
calls to virtual __attribute__((noreturn)) functions as noreturn; unlike GCC,
we do require overriders to also be noreturn for that attribute.

one-byte NOPs.  If the processor actually executes those NOPs, as it sometimes
does with aligned bundling, this can have a performance impact.  From my
micro-benchmarks run on my one machine, a 15-byte NOP followed by twelve
one-byte NOPs is about 20% worse than a 15 followed by a 12.  This patch
changes NOP emission to emit as many 15-byte (the maximum) as possible followed
by at most one shorter NOP.

We weren't treating a cf_audited_transfer CFRetain as returning +1 because

* Use the term 'command marker', because the semantics of 'backslash' and 'at'
  commands are the same.  (Talking about 'at commands' makes them look like a
  special entity.)

* Sink the flag down into bitfields, reducing the size of AST nodes.

* Change the flag into an enum for clarity.  Boolean function parameters are
  not very clear.

* Add unittests for new tok::at_command tokens.

Also fix a missing entry for cortex-r5 in one copy of getLLVMArchSuffixForARM.

llvm-svn: 176457

svn 170909 added support for cortex-r5 but in this case it was done
incorrectly. The last argument to StringSwitch.Cases() is the replacement
value, so by adding "cortex-r5" it changed the default cpu for armv7r to
cortex-r5 instead of cortex-r4.

DWARF with .o files now uses 40-60% less memory!

Big fixes include:
- Change line table internal representation to contain "file addresses". Since each line table is owned by a compile unit that is owned by a module, it makes address translation into lldb_private::Address easy to do when needed.
- Removed linked address members/methods from lldb_private::Section and lldb_private::Address
- lldb_private::LineTable can now relink itself using a FileRangeMap to make it easier to re-link line tables in the future
- Added ObjectFile::ClearSymtab() so that we can get rid of the object file symbol tables after we parse them once since they are not needed and kept memory allocated for no reason
- Moved the m_sections_ap (std::auto_ptr to section list) and m_symtab_ap (std::auto_ptr to the lldb_private::Symtab) out of each of the ObjectFile subclasses and put it into lldb_private::ObjectFile.
- Changed how the debug map is parsed and stored to be able to:
    - Lazily parse the debug map for each object file
    - not require the address map for a .o file until debug information is linked for a .o file
