c3b0c341e7 Avoid using f64 to lower memcpy from constant string. It's cheaper to use i32 store of immediates.

8ef5caa80a Revert this change from a while ago; ScalarEvolution shouldn't analyze
undef as 0, since it can't force other analyses to intepret the undef
in the same way.

701a4aef7f When expanding expressions which are using post-inc mode for multiple loops,
ensure that the expansion is dominated by the increments of those loops.

8f993b8c24 Added support for ARM disassembly to edis.
I also added a rule to the ARM target's Makefile to
build the ARM-specific instruction information table
for the enhanced disassembler.

I will add the test harness for all this stuff in
a separate commit.

6129c37693 convert a report_fatal_error that I was able to trigger into a nice error
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!

38686bdffd introduce a new recoverable error handling API to LLVMContext
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 :)

448db1cdef Generalize IVUsers to track arbitrary expressions rather than expressions
explicitly split into stride-and-offset pairs. Also, add the
ability to track multiple post-increment loops on the same expression.

This refines the concept of "normalizing" SCEV expressions used for
to post-increment uses, and introduces a dedicated utility routine for
normalizing and denormalizing expressions.

This fixes the expansion of expressions which are post-increment users
of more than one loop at a time. More broadly, this takes LSR another
step closer to being able to reason about more than one loop at a time.

5edca81626 Fixed a bug where the disassembler would allow an immediate
argument that had to be between 0 and 7 to have any value,
firing an assert later in the AsmPrinter.  Now, the
disassembler rejects instructions with out-of-range values
for that immediate.
