Greg Clayton d65ef14df3 Fixed breakpoints to be able to be set on eSymbolTypeReExported symbols and resolve to the correct function. This allows setting a breakpoint on "memset" for iOS simulator binaries and the correct breakpoint will be set on "__platform_memset".

Sergey Matveev fd10073aeb [lsan] When detect_leaks=false, be completely silent.
In particular, don't make a fuss if we're passed a malformed suppressions file,
or if we have trouble identifying ld.so. Also, make LSan interface functions
no-ops in this case.

David Blaikie 980d4994b2 DWARF type hashing: Handle multiple (including recursive) references to the same type
This uses a map, keeping the type DIE numbering separate from the DIEs
themselves - alternatively we could do things the way GCC does if we
want to add an integer to the DIE type to record the numbering there.

Greg Clayton 9191db47da <rdar://problem/14496092>
Fixed an issue with reexported symbols on MacOSX by adding support for symbols re-exporting symbols. There is now a new symbol type eSymbolTypeReExported which contains a new name for the re-exported symbol and the new shared library. These symbols are only used when a symbol is re-exported as a symbol under a different name.

Modified the expression parser to be able to deal with finding the re-exported symbols and track down the actual symbol it refers to.

Samuel Benzaquen f46e5f1c9a Refactor DynTypedMatcher into a value type class, just like Matcher<T>.
Summary:
Refactor DynTypedMatcher into a value type class, just like Matcher<T>.
This simplifies its usage and removes the virtual hierarchy from Matcher<T>.
It also enables planned changes to replace MatcherInteface<T>.
Too many instantiaions of this class hierarchy has been causing Registry.cpp.o to bloat in size and number of symbols.

Lang Hames 2783993fca X86 vector element shift-by-immediate instructions take i8 immediates. Make
the instruction defenitions and ISEL reflect this.

Prior to this patch these instructions took an i32i8imm, and the high bits were
dropped during encoding. This led to incorrect behavior for shifts by
immediates higher than 255. This patch fixes that issue by detecting large
immediate shifts and returning constant zero (for logical shifts) or capping
the shift amount at an encodable value (for arithmetic shifts).

David Blaikie f244319cac DebugInfo: Put each kind of constant (form, attribute, tag, etc) into its own enum for ease of use.
This allows various variables to be more self-documenting and easier to

Rafael Espindola 3d7fc25c7c Optimize more linkonce_odr values during LTO.
When a linkonce_odr value that is on the dso list is not unnamed_addr
we can still look to see if anything is actually using its address. If
not, it is safe to hide it.

This patch implements that by moving GlobalStatus to Transforms/Utils
and using it in Internalize.

David Blaikie 63bb3e1182 DebugInfo: Hash DW_FORM_GNU_str_index as a string.
Found while adding type safety to the various DWARF enumerations (form,
attribute, tag, etc) that caused Clang to warn on an incompletely
covered switch. Converting the comment to a default/unreachable
uncovered this case of an unsupported form encoding. Seems we were
skipping fission strings entirely.

Matheus Almeida a591fdc63c [mips][msa] Direct Object Emission support for CTCMSA and CFCMSA.
These instructions are logically related as they allow read/write of MSA control registers.
Currently MSA control registers are emitted by number but hopefully that will change as soon 
as GAS starts accepting them by name as that would make the assembly easier to read.

Serge Pavlov 6652921d5a Fix to PR8880 (clang dies processing a for loop).
Due to statement expressions supported as GCC extension, it is possible
to put 'break' or 'continue' into a loop/switch statement but outside its
body, for example:

    for ( ; ({ if (first) { first = 0; continue; } 0; }); )

Such usage must be diagnosed as an error, GCC rejects it. To recognize
this and similar patterns the flags BreakScope and ContinueScope are
temporarily turned off while parsing condition expression.

Justin Bogner 5353513058 Lex: Don't restrict legal UCNs when preprocessing assembly
The C and C++ standards disallow using universal character names to
refer to some characters, such as basic ascii and control characters,
so we reject these sequences in the lexer. However, when the
preprocessor isn't being used on C or C++, it doesn't make sense to
apply these restrictions.

Notably, accepting these characters avoids issues with unicode escapes
when GHC uses the compiler as a preprocessor on haskell sources.
