Add versions of __aeabi_memset and __aeabi_memclr which do not use mov
instructions between low registers, as this is unsupported on thumbv4t
and thumbv5.
errors as reported on macOS w/ Xcode 10.1, 10.2 and 11.0:
src/ir.cpp:23285:16: error: variable 'bits' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized]
} else if (float_type->id == ZigTypeIdFloat)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
src/ir.cpp:23288:13: note: uninitialized use occurs here
switch (bits) {

src/ir.cpp:23285:12: note: remove the 'if' if its condition is always true

unsigned bits;
and expand @sqrt
This revealed that the accuracy of ln is not as good as the current algorithm in
musl and glibc, and should be ported again.
v2: actually include tests
v3: fix reversal of in and out arguments on f128M_sqrt()
add test for @sqrt on comptime_float
do not include @nearbyInt() until it works on all targets.
This removes the odd width and precision specifiers found and replacing
them with the more consistent api described in #1358.
Take the following example:
{1:5.9}
This refers to the first argument (0-indexed) in the argument list. It
will be printed with a minimum width of 5 and will have a precision of 9
(if applicable).
Not all types correctly use these parameters just yet. There are still
some missing gaps to fill in. Fill characters and alignment have yet to
be implemented.
f8f054b354 exposes the issue where
macho symbol `__mh_execute_header` is weak exported with an extra
underscore and stack traces fail due to invalid header magic.
