Merge pull request #142 from jserv/clarify-ldpreload 
Clarify LD_PRELOAD on dynamically-linked ELF

61e4b83f36 Clarify LD_PRELOAD on dynamically-linked ELF 
LD_PRELOAD is an environment variable that can be set to load ELF
shared objects before all others. Linux and BSD are known to fit.
This change also unifies the use of command line, ensuring the prefix
"> " prompt.

99e071cf2c Link with -lrt for older glibc 
Quoted from Linux Programmer's Manual (2017-09-15):
    #include <time.h>
    int clock_gettime(clockid_t clk_id, struct timespec *tp);
    Link with -lrt (only for glibc versions before 2.17).

This patch adds additional checks for librt availability and append
target_link_libraries accordingly. librt is absent on macOS.

Merge pull request #126 from JeanMiK/fix_C++_signature_of_mi_is_in_heap_region 
Fix C++ signature of function mi_is_in_heap_region

3f43cbe6a1 Fix C++ signature of function mi_is_in_heap_region 
Original code did not compile with MI_USE_CXX=ON as function
mi_is_in_heap_region was declared noexcept through macro mi_attr_noexcept
but defined without specification, i.e. implicitly with noexception(false)

Just adding the macro in the definition is enough to fix the issue
(tested with gcc 8.3.5)

1ffa48cc61 Add branch prediction hint for mi_option_get 
mi_option_get is called frequently in stress tests, and the patch adds
extra hint to the compiler to emit instructions that will cause branch
prediction to favour the "likely" side of a jump instruction.

afd981d008 Use checked unsigned multiplication extension of GCC/Clang 
Most processors have carry flags which they set on addition overflow, so
it is a good idea to access them whenever possible. Most of them also
have widening multiply instructions that can be used to detect overflow
of the non-widening version. Both GCC and Clang offer a way to detect an
overflow for security critical applications.
