d5b7c28519 Ignore DBG_VALUE machine instructions while constructing instruction ranges based on location info.
Machine instruction range consisting of only DBG_VALUE MIs only contributes consecutive labels in assembly output, which is harmless, and empty scope entry in DebugInfo, which confuses debugger tools.

aa16fd02ad Do not model all INLINEASM instructions as having unmodelled side effects.
Instead encode llvm IR level property "HasSideEffects" in an operand (shared
with IsAlignStack). Added MachineInstrs::hasUnmodeledSideEffects() to check
the operand when the instruction is an INLINEASM.

This allows memory instructions to be moved around INLINEASM instructions.

324f849088 remove the verbose-asm "constant pool double" comments that we were printing
for each constant pool entry.  Using WriteTypeSymbolic here takes time
proportional to the size of the module, for each constant pool entry.

This speeds up -verbose-asm llc on 252.eon (a random testcase at my disposal)
from 4.4s to 2.137s.  llc takes 2.11s with asm-verbose off, so this is now a
pretty reasonable cost for verbose comments.

93a07b464e Change CodeGen to use .loc directives. This produces a lot more readable output
and testing is easier.  A good example is the unknown-location.ll test that
now can just look for ".loc 1 0 0".  We also don't use a DW_LNE_set_address for
every address change anymore.

5faff99d84 With the newly simplified SourceMgr interfaces and the generalized
SrcMgrDiagHandler, we can improve clang diagnostics for inline asm:
instead of reporting them on a source line of the original line,
we can report it on the correct line wherever the string literal came
from. For something like this:

void foo() {
  asm("push %rax\n"
      ".code32\n");
}

we used to get this: (note that the line in t.c isn't helpful)

t.c:4:7: error: warning: ignoring directive for now
  asm("push %rax\n"
      ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

now we get:

t.c:5:8: error: warning: ignoring directive for now
      ".code32\n"
       ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

Note that we're pointing to line 5 properly now.

99b8654169 now that AsmPrinter::EmitInlineAsm is factored right, we can eliminate the
cookie argument to the SourceMgr diagnostic stuff.  This cleanly separates
LLVMContext's inlineasm handler from the sourcemgr error handling 
definition, increasing type safety and cleaning things up.
