7b764d4173 tests/tcg: i386: extend BMI test
Cover all BMI1 and BMI2 instructions, both 32- and 64-bit.

Due to the use of inlines, the test now has to be compiled with -O2.

75b208c283 target/i386: fix operand order for PDEP and PEXT
For PDEP and PEXT, the mask is provided in the memory (mod+r/m)
operand, and therefore is loaded in s->T0 by gen_ldst_modrm.
The source is provided in the second source operand (VEX.vvvv)
and therefore is loaded in s->T1.  Fix the order in which
they are passed to the helpers.
