Late last year r191835 removed a largely unmaintained legacy PGO
infrastructure, but some of the docs were missed. Since these docs are
for things that don't actually exist anymore, they should be removed.

Change --functions option in llvm-symbolizer tool to accept
values "none", "short" or "linkage". Update the tests and docs
accordingly.

This option caused LowerInvoke to generate code using SJLJ-based
exception handling, but there is no code left that interprets the
jmp_buf stack that the resulting code maintained (llvm.sjljeh.jblist).
This option has been obsolete for a while, and replaced by
SjLjEHPrepare.
This leaves the default behaviour of LowerInvoke, which is to convert
invokes to calls.

Some references to llvm-gcc were so crusty that I wasn't sure how to
proceed and so I've left them intact.
I also slipped in a quick peephole fix to use a :doc: link instead of
raw HTML link.

Introducing llvm-profdata, a tool for merging profile data generated by
PGO instrumentation in clang.
- The name indicates a file extension of <name>.profdata. Eventually
profile data output by clang should be changed to that extension.
- llvm-profdata merges two profiles. However, the name is more general,
since it will likely pick up more tasks (such as summarizing a single
profile).
- llvm-profdata parses the current text-based format, but will be
updated once we settle on a binary format.

This change makes test with RUN lines like
RUN: opt ... | FileCheck
fail if opt fails, even if it prints what FileCheck wants. Enabling this
found some interesting cases of broken tests that were not being noticed
because opt (or some other tool) was crashing late.
Pipefail is used when the shell supports it or when using the internal
python based tester.
