89a2566e01 Add separate variants of memory built-ins for floats and doubles. 
Previously, we'd bitcast e.g. a vector of floats to a vector of i32s and then
use the i32 variant of masked_load/masked_store/gather/scatter.  Now, we have
separate float/double variants of each of those.

1ac3e03171 Gather/scatter function improvements in builtins. 
More naming consistency: _i32 rather than i32, now.

Also improved the m4 macros to generate these sequences to not require as
many parameters.

b86d40091a Improve naming of masked load/store instructions in builtins. 
Now, use _i32 suffixes, rather than _32, etc.  Also cleaned up the m4
macro to generate these functions, using WIDTH to get the target width,
etc.

91d22d150f Update load_and_broadcast built-in 
Change function suffix to "_i32", etc, from "_32"

Improve load_and_broadcast macro in util.m4 to grab vector width from 
WIDTH variable rather than taking it as a parameter.

f06caabb07 Generate better code for break statements in varying loops (sometimes). 
If we have a simple varying 'if' statement where the only code in the body is
a single 'break', then emit special case code that just updates the execution
mask directly.

Surprisingly, this leads to better generated code (e.g. Mandelbrot 7.1x on AVX
vs 5.8x before).  It's not clear why the general code generation path for
break doesn't generate the equivalent code; this topic should be investigated
further.  (Issue #277).

7b6bd90903 Remove various equality checks between GetInternalMask() and LLVMMaskAllOn 
These were never kicking in, since GetInternalMask() always loads from the
mask storage memory.

592affb984 Add experimental (and undocumented for now) export syntax. 
This allows adding types to the list that are included in the automatically-generated
header files.

struct Foo { . . . };
struct Bar { . . . };

export { Foo, Bar };

1397dbdabc Don't generate colorized output escapes when stderr isn't a TTY. 
When piping to a pile, more/less, etc, this is generally undesirable.

This behavior can be overridden with the --colorized-output command-line
flag.

8fd9b84a80 Update seed_rng() in stdlib to take a varying seed. 
Previously, we were trying to take a uniform seed and then shuffle that
around to initialize the state for each of the program instances.  This
was becoming increasingly untenable and brittle.

Now a varying seed is expected and used.

5084712a15 Fix bugs in examples/intrinsics/generic-64.h 
There were a number of situations where we were left-shifting 1 by a
lane index that were failing due to shifting beyond 32-bits.  Fixed
by shifting the 64-bit constant value 1ull.

64807dfb3b Add AssertPos() macro that provides rough source location in error 
It can sometimes be useful to know the general place we were in the program
when an assertion hit; when the position is available / applicable, this
macro is now used.

f4df2fb176 Improvements to mask update code for generic targets. 
Rather than XOR'ing with a temporary 'all-on' vector, we call
__not.  Also, we call out to __and_not1 and __and_not2, for an
AND where the first or second operand, respectively, has had
NOT applied to it.
