Fixed the Module::Module(ModuleSpec) constructor to properly copy the file offset and object file mod time from the actual module specifications so we will always be able to directly load the image we care about when calling Module::GetObjectFile().

This makes it slightly harder to misuse Twines.  It is still possible to
refer to destroyed temporaries with the regular constructors, though.

No longer allow the -std options to entirely override the -x language option. This allows -x cuda -std=c++11, for instance.

With -Weverything, the backend remarks are enabled. This was
causing spurious diagnostics for remarks that we don't yet
handle (cf http://reviews.llvm.org/D3683).

This will stop being a problem once http://reviews.llvm.org/D3683
is committed.

This seems to match what gcc does for ppc and what every other llvm
backend does.

This is a fixed version of r209638. The difference is to avoid any change
in behavior for functions. The logic for using constant pools for function
addresseses is spread over a few places and we have to keep them in sync.

The new storage (MetaMap) is based on direct shadow (instead of a hashmap + per-block lists).
This solves a number of problems:
 - eliminates quadratic behaviour in SyncTab::GetAndLock (https://code.google.com/p/thread-sanitizer/issues/detail?id=26)
 - eliminates contention in SyncTab
 - eliminates contention in internal allocator during allocation of sync objects
 - removes a bunch of ad-hoc code in java interface
 - reduces java shadow from 2x to 1/2x
 - allows to memorize heap block meta info for Java and Go
 - allows to cleanup sync object meta info for Go
 - which in turn enabled deadlock detector for Go

Fixing a test case which was failing the MSVC build bots. When -std isn't specified with an MSVC build, it defaults to -std=c++11, which overrides the -x cuda option. In turn, this causes all CUDA language option checks to fail.

This fix is possibly temporary while we determine whether -x cuda should be considered along with -std=c++11 when setting language options.

During loop-unroll, loop exits from the current loop may end up in in different
outer loop. This requires to re-form LCSSA recursively for one level down from
the outer most loop where loop exits are landed during unroll. This fixes PR18861.

[syserr.errcat.objects]p4 specifies that
system_category().default_error_condition(ev) map to
error_condition(posv, generic_category()) if ev could map to a POSIX
errno.

Linux reserves up to and including 4095 for errno values, use this as a
bound.

This fixes syserr.errcat.objects/system_category.pass.cpp on Linux.

to 'not inline', since that violates an AST invariant.
