merge XCore's section into MCSectionELF

api and update clients to use MCContext instead.

the compiler and asmparser now unique to the same sections.  This fixes

implicit defs get added to the end of machine instrs sometimes.  Scan the whole instruction for the metadata operand instead of assuming it will be at the end of the instruction.

There is no need to remember labels identifying regions marked by such instructions in each scope.

so the user at least knows what inline asm is a problem.  For example:

error: inline asm not supported yet: don't know how to handle tied indirect register inputs
pr8788-1.c:14:10: note: generated from here
    asm ("\n" : "+r" (stack->regs)
         ^

Instead of:
fatal error: error in backend: Don't know how to handle tied indirect register inputs yet!

llvm-svn: 100731

llvm-svn: 100725

llvm-svn: 100724

and use it in one place in inline asm handling stuff.  Before
we'd generate this for an invalid modifier letter:

$ clang asm.c -c -o t.o
fatal error: error in backend: Invalid operand found in inline asm: 'abc incl    ${0:Z}'
INLINEASM <es:abc incl    ${0:Z}>, 10, %EAX<def>, 2147483657, %EAX, 14, %EFLAGS<earlyclobber,def,dead>, <!-1>


Now we generate this:

$ clang asm.c -c -o t.o
error: invalid operand in inline asm: 'incl    ${0:Z}'
asm.c:3:12: note: generated from here
  __asm__ ("incl    %Z0" : "+r" (X));
           ^
1 error generated.

This is much better but still admittedly not great ("why" is the operand 
invalid??), codegen should try harder with its diagnostics :)
