940da2ce0e nir: Add missing break into switch in construct_value()
There seemed to be missing one break in nested switchcases.

3babb7b0a4 nir: Use PRIi64 and PRIu64 instead of %ld and %lu.
%ld and %lu aren't the right format specifiers for int64_t and uint64_t
on 32-bit (x86) systems.  They're %zu on Linux and %Iu on Windows.

Use the standard C99 macros in hopes that they work everywhere.

eb93d6dec8 nir/search: Don't match inexact expressions with exact subexpressions
In the first pass of implementing exact handling, I made a mistake with
search-and-replace.  In particular, we only reallly handled exact/inexact
on the root of the tree.  Instead, we need to check every node in the tree
for an exact/inexact match.  As an example of this, consider the following
GLSL code

precise float a = b + c;
if (a < 0) {
   do_stuff();
}

In that case, only the add will be declared "exact" and an expression that
looks for "b + c < 0" will still match and replace it with "b < -c" which
may yield different results.  The solution is to simply bail if any of the
values are exact when matching an inexact expression.

0bea0e7141 nir: fix dangling ssadef->name ptrs
In many places, the convention is to pass an existing ssadef name ptr
when construction/initializing a new nir_ssa_def.  But that goes badly
(as noticed by garbage in nir_print output) when the original string
gets freed.

Just use ralloc_strdup() instead, and add ralloc_free() in the two
places that would care (not that the strings wouldn't eventually get
freed anyways).

Also fixup the nir_search code which was directly setting ssadef->name
to use the parent instruction as memctx.

58fe7837b8 nir: propagate bitsize information in nir_search
When we replace an expresion we have to compute bitsize information for the
replacement. We do this in two passes to validate that bitsize information
is consistent and correct: first we propagate bitsize from child nodes to
parent, then we do it the other way around, starting from the original's
instruction destination bitsize.

v2 (Iago):
- Always use nir_type_bool32 instead of nir_type_bool when generating
  algebraic optimizations. Before we used nir_type_bool32 with constants
  and nir_type_bool with variables.
- Fix bool comparisons in nir_search.c to account for bitsized types.

v3 (Sam):
- Unpack the double constant value as unsigned long long (8 bytes) in
nir_algrebraic.py.

v4 (Sam):
- Use helpers to get type size and base type from nir_alu_type.
