fix uc_mem write with cow when using upper half of the address
...
uc->target_page_align is a uint32_t. When the binary not will only
invert the 32 bit of the value. Used this in a binary and operator with
a uint64_t will case the upper 32bit of the address to be 0. Therefor
the bug only appears when the upper 32bit of the address are used.
Now a local uint64_t variable is used for the alignemend and the test
uses a not page alligned address which does not fit in 32bit.

uc_ctl_flush_tlb implies that the tlb is flushed. This change adds
UC_CTL_TLB_FLUSH which clears the TLB and set the uc_ctl_flush_tlb
alias to UC_CTL_TLB_FLUSH. Also adds a uc_ctl_flush_tb alias for
UC_CTL_TB_FLUSH.

Remove MMU hacks

Unicorn has included some ugly hacks to provide a envirement where vaddr == paddr.
These hacks where to use the full 64 bit mappings on x86 without init the mmu

The UC_TLB_CPU mode defaults to vaddr == paddr, therfor these hacks aren't
required anymore.

quit_request is for internal use. This means the IP register was updated and
