5f2f5fa638 Be nice to Xcore and the XMOS assembler and avoid quoting section names
that contain only letters, digits and the characters "_" and ".".

3c32af5834 Switch llvm to using comdats. For now always use groups with a single
section.

3c0f11a265 Fixed version of 118639 with an extra assert to catch similar problems
earlier. Implicit bool -> int conversions are evil!

9c76bbf90a Add hook in MCSection to decide when to use "optimized nops", for each
section kind. Previously, optimized nops were only used for MachO.
Also added tests for ELF and COFF.

7df9bf0092 Move logic of determining ELF entsize from the .s printer to initialization
time. That way, the EntrySize field is initialized for other code paths, 
namely, the .ll -> .o code path.

3665e2058e add support for target-specific ELF section flags, add a new MCSectionXCore
class which represents the XCore cp/dp section flags.  No functionality
change yet.

3497fde219 Fix MCSectionELF::ShouldOmitSectionDirective's matching of .data and
friends so that it doesn't match sections like .data.rel.local, which
should not be emitted as section directives.

f2855aabec Change MCSectionELF to represent a section semantically instead of
syntactically as a string, very similiar to what Chris did with MachO.
The parsing support and validation is not introduced yet.
