Summary:
Port the ReconstructShuffle function from AArch64 to ARM
to handle mismatched incoming types in the BUILD_VECTOR
node.

This fixes an outstanding FIXME in the ReconstructShuffle

Summary: WebAssembly's tablegen instructions have the names WebAssembly expects, but by LLVM convention they're uppercase and suffixed with their type after an underscore. Leave the C++ code that way, but print outt he names WebAssembly expects (lowercase, no type). We could teach tablegen to do this later, maybe by using `!cast<string>(node)` in the .td files.

As a follow-up to r244181, resolve uniquing cycles underneath distinct
nodes on the fly.  This prevents uniquing cycles in early operands from
affecting later operands.  It also removes an iteration through distinct
nodes' operands.

No real functional change here, just more prompt resolution of temporary
nodes.

Pull out a helper for resolving uniquing cycles of `Metadata` to remove

The block address machine operands can reference IR blocks in other functions.
This commit fixes a bug where the references to unnamed IR blocks in other
functions weren't serialized correctly.

This commit removes the 'StringOffset' and 'HasStringValue' fields from the
MIToken struct and simplifies the 'stringValue' method which now returns
the new 'StringValue' field.

This commit also adopts a different way of initializing the lexed tokens -
instead of constructing a new MIToken instance, the lexer resets the old token
using the new 'reset' method and sets its attributes using the new
'setStringValue', 'setOwnedStringValue', and 'setIntegerValue' methods.

When we are not emitting the condition for the branch, because the condition is
in another BB or SDAG did the selection for us, then we have to mask the flag in
the register with AND.

This is required when the condition comes from a truncate, because SDAG only
truncates down to a legal size of i32.

This fixes rdar://problem/22161062.

llvm-svn: 244291

Revert "[AArch64][FastISel] Add more truncation tests." and "[AArch64][FastISel] Always use an AND instruction when truncating to non-legal types."

This reverts commit r243198 and 243304.

Turns out this wasn't the correct fix for this problem. It works only within
FastISel, but fails when the truncate is selected by SDAG.

lld might end up using a small part of this, but it will be in a much

Summary:
This adds somewhat basic preparation functionality including:
- Formation of funclets via coloring basic blocks.
- Cloning of polychromatic blocks to ensure that funclets have unique
  program counters.
- Demotion of values used between different funclets.
- Some amount of cleanup once we have removed predecessors from basic
  blocks.
- Verification that we are left with a CFG that makes some amount of
  sense.

N.B. Arguments and numbering still need to be done.

A dSYM bundle is a file hierarchy that looks slike this:
 <bundle name>.dSYM/
     Contents/
        Info.plist
        Resources/
           DWARF/
              <DWARF file(s)>

This is the default output mode of dsymutil.

llvm-svn: 244270

dsymutil should by default generate dSYM bundles which are filesystem
hierarchies containing the debug info and an additional Info.plist.
Currently llvm-dsymutil emits raw binaries containing the debug info.
This is what we call the 'flat mode'. Add a -f/-flat option that is
supposed to enable that flat mode, but don't wire it for now, only
pass it to the tests that will need it to stay functional once we
do bundle generation by default.
This basically makes this commit NFC and removes the noise from the
actual commit that adds support for bundle generation.
