Hardcode ziggurat tables
Bump openlibm and openspecfun.
Steps towards MSVC compatibility

Add USEMSVC variable to Make.inc for handling different flags and toolchain

Fix LLVM header problem in codegen.cpp due to define on min/max

Use __cpuid intrinsic for msvc instead of inline assembly

Add explicit casts, fixup ifdefs (_WIN32 instead of __WIN32__)
Updates for MSVC

patch utf8proc so it can compile in either C or C++ mode

dont define USE_COMPUTED_GOTO for MSVC
(might be an odd double-definition problem from some header)

add utf8proc info to src/flisp/Windows.mk
(needs some improvement on handling of utf8proc
version number and assumption of cl vs icl)

add strtod to Windows.mk

add DLLEXPORT before jl_init_frontend(void)

modify OSLIBS and CONFIGURE_COMMON for msvc
Minor MSVC changes

compile basename and dirname for msvc

disable line endings error

define HUGE_VALF if needed

add shell32.lib and winmm.lib to OSLIBS

modify preprocessing for MSVC

add include path to openlibm for fenv.h
Enforce C linkage everywhere

in order to compile Julia with a C++ compiler (specifically MSVC)
adjust linker invocation for msvc

skip flisp unit test with msvc (for now?)

skip a few headers (will need to find replacements for these)
Work to get basic REPL to compile with MSVC

explicit casts and fix ifdefs (__WIN32__ => _WIN32)

remove unistd header already included in repl.h

remove DLLEXPORT from repl.h

use hex code for escape

put back getopt.h

define dirname and PATH_MAX for repl

fix LDFLAGS that MSVC doesn't understand

skip julia_res.o with msvc

extern C linkage on repl
REPL now compiles with MSVC

crashes immediately, but it's a start

extern C on basename, dirname, jlapi

DLLEXPORT on basename, dirname

add export to link command for jl_setjmp and jl_longjmp

get uv to export symbols
another explicit cast for libuv bump
extern C on jl_in_stackwalk
skip EXCEPTION_EXECUTE_HANDLER case for MSVC
Bind meta-backspace

REPL: Bind meta-backspace to delete previous word
Fix test_approx_eq with complex NaNs
Explain "x < 0 && return 1" idiom

In the section on Conditional Evaluation, highlight Short-Circuit Evaluation as an alternative for very short if-statements.
In the section on Short-Circuit Evaluation, explain the idiom of "condition && statement", "condition || statement". 
Note that I don't know how this "doctest" stuff works, pls check my submission for correctness (I've copied/pasted straight from a Julia REPL).

Explain "x < 0 && return 1" idiom
fix #6333 (repl tab completion replaces too much)
Add a kill buffer and implement yanking

Binds control-y to yank. The kill buffer (not a real kill-ring) is stored in MIState.
