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.

Improved the misc-move-constructor-init check to identify arguments that are passed by value but copy assigned to class data members when the non-deleted move constructor is a better fit.

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.

Summary:
The assembly printing of these is still missing the encoding size
suffix, but this will be fixed in a later commit.

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.

This is passing 50/50 times for me.  Moving to flaky as precautionary
measure.

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.

Summary:
This fixes 7 tests during fast LLVM test-suite run:
* MultiSource/Benchmarks/McCat/18-imp/imp
* MultiSource/Applications/oggenc/oggenc
* MultiSource/Benchmarks/MallocBench/gs/gs
* MultiSource/Benchmarks/MiBench/automotive-susan/automotive-susan
* MultiSource/Benchmarks/VersaBench/beamformer/beamformer
* MultiSource/Benchmarks/MiBench/consumer-lame/consumer-lame
* MultiSource/Benchmarks/Bullet/bullet

Error message was in the form of:
fatal error: error in backend: Cannot select: 0x95c3288: f32 = fsqrt 0x95c0190 [ORD=9] [ID=18]
  0x95c0190: f32 = fadd 0x95bef30, 0x95c4d00 [ORD=8] [ID=17]
    0x95bef30: f32 = fmul 0x95c4988, 0x95c4988 [ORD=5] [ID=16]
...

There was problem with selecting sqrt instruction in LLVM backend.

To fix the issue changes are made in TableGen definition for sqrt instruction in MipsInstrFPU.td and new test file sqrt.ll is added to LLVM regression tests.

This test case was XFAILed under the assumption Polly is unable to detect the
scop. However, disabling Polly's profitability heuristics is sufficient to
detect this scop.

By disabling our scop-profitability heuristics this becomes also visible in some
older test cases.

ASTUnit was creating multiple FileManagers and throwing them away. Reuse
the one from Tooling. No functionality change now but necessary for
VFSifying tooling.

It took me some time to figure out why this is not working as expected:
std:error_code converts to true if there is an error. This means we never
ever took the generated absolute path, which happens to be the right thing
anyways as it properly works with virtual files. Just remove the whole
thing, relative paths are covered by existing tooling tests.

llvm-svn: 249408

Rename the python source file for DataFormatterOSTypeTestCase to match
the purpose of the test and to avoid a name conflict with
DataFormatterBoolRefPtr. The name conflict caused a race condition in
the test runner what we have to address separately.

llvm-svn: 249407

This is a case that requires --start-group --end-group with regular ELF
linkers. Fortunately it is still possible to handle it with lazy symbols without
taking a second look at archives.
