autoconf: Fix libLLVM-Major-Minor-Patch.so symlink

Teach the inliner how to preserve musttail invariants

The interesting case is what happens when you inline a musttail call
through a musttail call site.  In this case, we can't break perfect
forwarding or allow any stack growth.

Instead of merging control flow from the inlined return instruction
after a musttail call into the body of the caller, leave the inlined
return instruction in the caller so that the musttail call stays in the
tail position.

More work is required in http://reviews.llvm.org/D3630 to handle the
case where the inlined function has dynamic allocas or byval arguments.

[DWARF parser] Use enums instead of bitfields in DILineInfoSpecifier.

It is more appropriate than the current situation, when one flag
(AbsoluteFilePath) is relevant only if another flag is set.

This refactoring would also simplify fetching the short function name
(stored in DW_AT_name) instead of a linkage name returned currently.

No functionality change.

DebugInfo: Don't put fission type units in comdat sections.

Since type units in the dwo file are handled by a debug aware tool, they
don't need to leverage the ELF comdat grouping to implement
deduplication. Avoid creating all the .group sections for these as a
space optimization.

Implement global merge optimization for global variables.

This commit implements two command line switches -global-merge-on-external
and -global-merge-aligned, and both of them are false by default, so this
optimization is disabled by default for all targets.

For ARM64, some back-end behaviors need to be tuned to get this optimization
further enabled.
