remove DebugLoc from MCInst and eliminate "Comment printing" from

the MCInst path of the asmprinter. Instead, pull comment printing
out of the autogenerated asmprinter into each target that uses the

target, but in a way that will be easier to clean up later when more
asmprinter stuff is commonized into the base AsmPrinter class.

Clone functions that are shared between the Main thread and Interrupt thread.
CallSites are changed in AsmPrinter currently. A better solution would have been to modify the legalizer (SoftenFloat) to allow targets to change the name of libcalls for float operations. But that currently breaks other targets.
Also, cloing of automatic variables is done AsmPrinter, a better approach would
be to use the ValueMap in CloneFunction itself.

An overhaul of the exception handling code. This is arguably more correct than
...
what was there before. In "no FP mode", we weren't generating labels and unwind
table entries after each "push" instruction. While more than likely "okay", it's
not technically correct. The major thing was that the ordering of when to define
a new CFA register and at what offset wasn't correct. This would cause the
exception handling to fail in ways most miserable to users.
I also cleaned up some code a bit. There's one function which has a "return" at
the beginning, so it's never used. Should I just remove it? :-)

use XCore-specific section with xcore specific cp/dp flags to restore
...
support for globals going into the appropriate sections with the flags.
This hopefully finishes unbreaking the previous behavior that I broke before.

If ELF subtargets don't want to support 4/8/16-byte mergable sections, allow
...
them to null out the default section pointers.

On x86-64, for a varargs function, don't store the xmm registers to
...
the register save area if %al is 0. This avoids touching xmm
regsiters when they aren't actually used.

Allow targets to specify their choice of calling conventions per
...
libcall. Take advantage of this in the ARM backend to rectify broken
choice of CC when hard float is in effect. PIC16 may want to see if
it could be of use in MakePIC16Libcall, which works unchanged.
