Hexagon (target/hexagon) fix store w/mem_noshuf & predicated load
Call the CHECK_NOSHUF macro multiple times: once in the
fGEN_TCG_PRED_LOAD() and again in fLOAD().
Before this commit, a packet with a store and a predicated
load with mem_noshuf that gets encoded like this:
{ P0 = cmp.eq(R17,#0x0)
memw(R18+#0x0) = R2
if (!P0.new) R3 = memw(R17+#0x4) }
... would end up generating a branch over both the load
and the store like so:
...
brcond_i32 loc17,$0x0,eq,$L1
mov_i32 loc18,store_addr_1
qemu_st_i32 store_val32_1,store_addr_1,leul,0
qemu_ld_i32 loc16,loc7,leul,0
set_label $L1
...
Test cases added to tests/tcg/hexagon/mem_noshuf.c
