Factor out some common code used to get+set function prefix/prologue
data. This may come in handy if we ever decide to store personality
functions in the same way we store prefix/prologue data.

Summary:
Assign one state number per handler/funclet, tracking parent state,
handler type, and catch type token.
State numbers are arranged such that ancestors have lower state numbers
than their descendants.

- Add CoreCLR to if/else ladders and switches as appropriate.
- Rename isMSVCEHPersonality to isFuncletEHPersonality to better
reflect what it captures.

This is a cleaned up patch from the one written by John Regehr based on the findings of the Souper superoptimizer.
When writing tests, I was surprised to find that instsimplify apparently doesn't know how to collapse bit test sequences based purely on known bits. This required me to split my tests across both instsimplify and instcombine.

Go tests fail on Ubuntu 14.04's go1.2.1. This change puts a minimum
go version in the skipUnlessGoInstalled() decorator of go1.3.0.
Go maintainers are encouraged to modify as needed. For now this fixes
failing tests on Ubuntu 14.04 x86_64 buildbots with stock distro go installed.

The spec says (section 6.12.3, CL version 1.2):
The macro names given in the following list must use the values
specified. The values shall all be constant expressions suitable
for use in #if preprocessing directives.
This commit addresses the second part of that statement.

As mentioned in the bug, I'd missed the presence of a getScalarType in the caller of the new implies method. As a result, when we ended up with a implication over two vectors, we'd trip an assert and crash.

Right now clang_Cursor_getMangling will attempt to mangle any
declaration, even if the declaration isn't mangled (extern "C"). This
results in a partially mangled name which isn't useful for much. This
patch makes clang_Cursor_getMangling return an empty string if the
declaration isn't mangled.

This single option replaces -polly-detect-unprofitable and -polly-no-early-exit
and is supposed to be the only option that disables compile-time heuristics that
aim to bail out early on scops that are believed to not benefit from Polly
optimizations.

These flags are now always passed to all tests and need to be disabled if
not needed. Disabling these flags, rather than passing them to almost all
tests, significantly simplfies our RUN: lines.

4-core CPUs have a hard time keeping up with the number of debuggers
we were simultaneously spawning. This leads to a timeout, which
leaves processes hanging around in "suspended mode", which can't be
killed with signals.

Polly's profitability heuristic saves compile time by skipping trivial scops or
scops were we know no good optimization can be applied. For almost all our tests
this heuristic makes little sense as we aim for minimal test cases when testing
functionality. Hence, in almost all cases this heuristic is better be disabled.
In preparation of disabling Polly's compile time heuristic by default in the
test suite we first explicitly enable it in the couple of test cases that really
use it (or run with/without heuristic side-by-side).

We were still fetching them when the archive was seen first.
We should experiment with just letting lazy symbols get to compare, it
might be cleaner for ELF.
