[mips] Replace usages of register classes with register operands. Also, remove
unnecessary jalr InstAliases in Mips64InstrInfo.td and add the code to print
jalr InstAliases in MipsInstPrinter::printAlias.

Remove some std stream usage from Support and TableGen

LLVM's coding standards recommend raw_ostream and MemoryBuffer for
reading and writing text.

This has the side effect of allowing clang to compile more of Support
and TableGen in the Microsoft C++ ABI.

Change the linkage of these global values to 'internal'.

The globals being generated here were given the 'private' linkage type. However,
this caused them to end up in different sections with the wrong prefix. E.g.,
they would be in the __TEXT,__const section with an 'L' prefix instead of an 'l'
(lowercase ell) prefix.

The problem is that the linker will eat a literal label with 'L'. If a weak
symbol is then placed into the __TEXT,__const section near that literal, then it
cannot distinguish between the literal and the weak symbol.

Part of the problems here was introduced because the address sanitizer converted
some C strings into constant initializers with trailing nuls. (Thus putting them
in the __const section with the wrong prefix.) The others were variables that
the address sanitizer created but simply had the wrong linkage type.

[mips] Mark instructions defined in Mips64InstrInfo.td that are duplicates of

[NVPTX] We dont have any target specific flags yet for generating symbol references, so get rid of the default-only switch statement.  Fixes an MSVC warning.

R600/SI: Add more special cases for opcodes to ensureSRegLimit()

Also factor out the register class lookup to its own function.

R600/SI: Use VSrc_* register classes as the default classes for types

Since the VSrc_* register classes contain both VGPRs and SGPRs, copies
that used be emitted by isel like this:

SGPR = COPY VGPR

Will now be emitted like this:

VSrC = COPY VGPR

This patch also adds a pass that tries to identify and fix situations where
a VGPR to SGPR copy may occur.  Hopefully, these changes will make it
impossible for the compiler to generate illegal VGPR to SGPR copies.

Replacing /GR with /GR- instead of applying both options to the project.  This should reduce some build bot warnings (D9025: "overriding '/GR' with '/GR-'").

Implemented llvm::sys::locale::columnWidth and isPrint for the case of generic UTF8-capable terminal.

Summary:
This is a second attempt to get this right. After reading the Unicode
Standard I came up with the code that uses definitions of "printable" and
"column width" more suitable for terminal output (i.e. fixed-width fonts and
special treatment of many control characters).
The implementation here can probably be used for Windows and MacOS if someone
can test it properly.
The patch addresses PR14910.

Check for _strtoi64 in the cmake build if strtoll is missing

Previously this check was guarded by MSVC, which doesn't distinguish
between the compiler and the headers/library.  This enables clang to
compile more of LLVM on Windows with Microsoft headers.

Remove some unused macros while I'm here: error_t and LTDL stuff.

Avoid using alloca in Windows/Program.inc

One use needs to copy the alloca into a std::string, and the other use
is before calling CreateProcess, which is very heavyweight anyway.
